Trips, restorations or anything else you think might be of interest

Renewing the front brakes on my ’73 Bay, Mortimer Henderson

By Jonathan Bruton

CAVEAT: brakes are obviously safety-critical components, so only attempt this job if you are confident that you can do so safely! This is a personal account of a process and not an exhaustive set of instructions; the author cannot be held liable for any injury arising from accidents caused by a failure to carry out safety-relevant tasks properly.

Some while ago, in that pre-Covid world in which we could drive places (remember that?), I started to become aware of a tell-tale grinding noise coming from Mortimer’s nearside front wheel. There still seemed to be adequate braking power, nor was the van pulling particularly in either direction when I applied the brakes, so I wasn’t unduly concerned. But I thought I’d take advantage of the lockdown to jack him up, whip off the wheels and take a look at the callipers and brake discs.

The old caliper

You can imagine my horror when I saw that, in the first assembly I looked at on the nearside, the calliper pistons were frozen in such a way that the brake pads must have been forced up against the disc surface. The pistons normally only protrude slightly from the inner surfaces of the calliper, allowing enough space to snugly fit the two pads with a tiny bit of clearance. But as  you can see on the picture, the dirt seals – concertina boots that should move in and out with the piston and protect it from contamination – had long since perished and the pistons had accordingly seized up in extended position. On closer inspection, it also became apparent that there was zero friction material left on either pad(!) – what I was hearing was metal on metal. Whatever braking performance there may once have been was obviously a thing of the distant past! The disc surface was as scored and uneven as you would expect under those circumstances, and the disc was obviously beyond redemption. Things were a little better on the other side, with some wear left on the pads – although the fact that van wasn’t pulling to the right suggests that that brake wasn’t functional either. I toyed with the idea of trying a rebuild but, when it became evident that there was no way I was going to get the bleed valves free, I thought I might as well save myself a lot of bother by buying new callipers for both wheels along with two new discs.

The worn brake pad

The first job, of course, was to get the old callipers off so I could remove the discs. This was relatively straightforward. I first had to undo the two 17mm retaining bolts on the inside of the assembly. I then used a pin punch to knock out the two pins that hold the retaining spring in place before tugging out the old pads. It was then a question of pulling out the clip that holds the hose in place and removing the whole assembly from the disc, being careful not to place undue strain on the metal brake pipe that attaches to the calliper. I also needed to bear in mind that the topmost bolt has an unthreaded section on the shank closest to the screw head. The nuts were pretty tight, however, and I needed a torque wrench to get them off. According to the BUSARU guy, the torque is about 110 lbs.

The top bolt

The tricky part in getting the discs off was removing the two button head Allen bolts. Stopping the drum from rotating was an issue until I had the brainwave of clamping the disc to the backing plate. I managed to free up one bolt on each side by conventional means but soon found myself in danger (of course!) of irredeemably rounding off the holes in the other two in my desperate attempts to get them to budge. I even resorted to cutting a groove into one of them (and the surrounding metal) with a grinder to create a slot for a screwdriver. But nothing could persuade it to move! A quick appeal to the Samba revealed a range of opinions on the subject, from just drilling the heads off (the logic being that the thing was securely held in place by the wheel anyway and wasn’t going to go anywhere) to using an impact driver. I like to do things properly if I possibly can, so it was off to eBay to get myself an impact driver (can’t believe I’ve never owned one!). And, hey presto, a couple of whacks on each side got the troublesome little critters out. I took a quick look at the condition of the bearings, which seemed fine and well-greased, so I left them alone. I then fitted the shiny new discs to both sides.

The shiny new disc

The next job was to disconnect the old callipers from the brake lines. Now, as the brakes are safety-critical parts, I’d always shied away from doing anything that would involve having to refill and bleed the fluid. But, having watched a number of YouTube videos on the subject, I concluded that I had nothing to fear but fear itself and went ahead. It would have been a good idea to apply some WD40 to the nuts first, though: on one side, the pipe started to twist with the nut (which should normally spin freely around it), which promptly sheared off. So it was back to Just Kampers for a new 24-cm brake pipe (I swear I’m keeping that company afloat single-handed at the moment!).

Offering the caliper to the disk

With the old units out of the way, it was just a matter of fixing the new ones in place, torqueing up the bolts, and sliding in the new brake pads and backing plates, having first applied some anti-squeal gunk to both sides of the plates. Once they were both in, it was the turn of the retaining spring and the two pins (here I reused the old ones because the new pins supplied with the kits resisted my efforts to tap them into the holes). I used a pin punch and hammer to tap them home.

The new caliper in place

Then it was just a question of bleeding the brakes, replacing the wheels and venturing out for a short road test (keeping an eye out for the police – strange times!). Job done!

Road trip gone bad: Not quite making it to Baja in my Westy

My Wesy takes a trip


Mexico’s Baja California peninsula is an incredibly beautiful place. My 1987 Volkswagen camper van can be an amazing way to travel there. As anyone who has been around one knows, however, calamity is part of every Westy adventure.

Two years and 10 thousand miles ago I completely rebuilt my VW Vanagon GL Westfalia. A day before a large holiday party, while running to pick up ALL THE FOOD, my Vanagon threw the alternator belt, overheated and in a disastrous chain of events ended up needing an engine, transmission, cooling system and brakes. I threw in a new tent and bigger, low profile wheels just for fun. I used GoWesty’s fantastic 2.3L upgraded power plant and made a slew of minor improvements. I had been having such a great two years with the bus, I started to think it was bulletproof.

“She’s like a new car!” I told my girlfriend, who had agreed to come with me on a trip to Canyon de Guadalupe, Mexico, before I described the long, long list of things I’d replaced or had done. We booked a campsite for a few days in late December and planned to marathon drive down from San Francisco on Christmas day.

I worried over every small detail. Swapping out an old p-trap under the kitchen sink in the van took 3 days. This should have been the first clue things were going to go wrong. I started out thinking I needed a better wrench to free it. I ended up drilling holes in the old trap to weaken it, and needing a saw to cut it out. Welcome to the world of the VW bus.

Then the fridge, after starting easily the first time I tried, refused to relight after I’d filled up the propane tank. “Oh well!” I thought, “I’ll run off of electric and start it on gas when I get to Mexico.” It gave me something to worry about, which I felt was normal, so I didn’t let it get in the way.

I’d labored over a decision: whether to take Highway 5 up and over the Grapevine, or the 101. As we were trying for speed, and I trusted my GoWesty engine, we chose the 5. Where to cross the international border was also a major consideration. I wanted to cross at Tecate and drive the famous, scenic MEX2 highway 150 or so miles through La Rumerosa to Laguna Salada and Canyon De Guadalupe. I was worried that Pemex, the state-owned and only gas stations in Mexico, might be closed on Christmas in more rural areas and thought we might run out of gas on our way North. To ensure that didn’t happen, we planned to cross at Mexicali.

I left Muir Beach, CA at 3:30AM, picked up my co-pilot in Oakland around 4 and we were off. She drove the first shift and I slept. Waking up once or twice at gas stops, I wasn’t really cogent or thinking as she headed up the Grapevine, California’s famous VW bus killer.

Many an air-cooled VW van has died on this monstrous incline. Named after the grapes that grow wild around the remnants of the earlier HWY99 that was long ago replaced by the 5, this section of road was once to be feared in the Summer. Nowadays cars have far more efficient cooling systems, as it helps regulate fuel efficiency (an important point later,) but my woefully underpowered 1987 van would have been in danger. Luckily, I thought, it has run super cool since the rebuild and December was freezing cold. I didn’t anticipate any trouble. I didn’t realize my co-pilot was unfamiliar with the Vanagon’s quirky, near useless, gas gauge.

We actually made it over the top of the Grapevine just fine! The van did well and held 55 most of the way. Once we came over the top, with her nose pointed down, we ran out of gas. Initially, I didn’t notice anything. My co-pilot complained she was losing power and I asked her to let off the gas. I took the car out of gear and immediately the engine stopped. Luckily, without the engine braking we sped up. We threw on the hazards and decided to try and roll to the next gas station in Gorman. We came up about 15 feet short and needed a slight push, but as far as Grapevine calamities go this was pretty mild. We filled up the tank, primed the fuel pump and she started right up.

It took about another hundred miles for things to go wrong. My best guess is that we sucked up a ton of sludge from the bottom of my new gas tank (did I mention that had been replaced 2 years ago as well?). It is possible we also got bad gas in Gorman, but they have so much traffic I find that less likely. Whatever the cause, the Vanagon gradually lost power until it wouldn’t rev over 3500rpm. That limited us to about 50-55mph on flat ground and 35mph or so uphill. We were trying to take the 210 freeway around Los Angeles to bypass traffic and didn’t anticipate the San Gabriel mountains being such a problem. Clearly something was wrong with the car.

We ran a little bit of fuel injector cleaner through the Westy. Things got better. We ran a lot more fuel injector cleaner through her and things got a lot better. I decided to swap the fuel filter, after I proudly told my traveling companion I had the foresight to carry one for just this type of problem. We would head from San Dimas, about 70 or 80 miles, with the car gaining and losing power, to Santa Monica and spend the night at my parents. In the AM I’d swap the filter and we’d head to Mexico.

Visiting Santa Monica let us have dinner at my favorite deli in West Los Angeles, Izzy’s. I am not a Fromin’s fan. Had we been closer to the San Fernando Valley, I’d have gone to Brent’s. It was wonderful to eat at a deli on Christmas.

The next morning I swung under the van, asking my friend to time me, because this was going to take less than 5 minutes. Then I saw that the bolt holding the fuel filter to the frame was stripped. It looked like someone had used a power tool on it while up on a lift and chewed the center out. I tried my fathers special “remove stripped bolts and screws” screwdriver to no avail. I tried vise grips but couldn’t get any purchase. Then I found a local mechanic who was open and for $20 he removed the bolt and swapped in the spare filter. It took him less than 5 minutes.

We were on our way! The car was running great again, we could hold 75mph no problem and O’Reilly Auto Parts had another spare fuel filter for us. We headed towards Mexico.

Around 40-50 miles later I noticed that the car felt like it was losing power when I floored it, a frequent occurrence in a vintage VW bus. I had no clue what was going on, so we stopped at a gas station. Idling the van for a few moments, I was surprised to see the temperature gauge never came up above minimum operating temps. I thought the thermostat might be stuck open. Luckily, my incredible mechanic Paul from San Rafael’s Valley Wagonworks chose that very moment to call me. We discussed the issues I’d been seeing and he suggested finding a Vanagon expert to swap the thermostat. He wondered if maybe a fuel injector was still clogged. He told me I wouldn’t hurt the van driving it like this, but it’d be slow.

I took a look at the thermostat housing and decided it was under too much junk to try and swap on the road. I wanted to go to Baja but I also just wanted to go home. The idea of finding myself stuck on the side of the road in Palm Springs, CA with the fluids pouring out of a cooling system I was unable to properly bolt down was only slightly more appealing than the idea of being in a similar position on the southern side of the US/Mexico border. It was around 11am and 70ºF out. The car was running fine. We agreed it’d be safer to just go home.

Thus began a long, slow trip home. I did not anticipate the outside temperatures changing. As it got colder the car lost power. As we went up in elevation, we lost power. The car ran less and less efficiently, sometimes down to 6 or 7mpg. We were stopping every 60-80 miles. When outside temperatures dropped below 50F the car started to blow clouds of smoke when you’d accelerate.

This was not how I’d hoped to introduce a new friend to the joys of Vanagon camping.

We got home. During the several days we spent pretending my house was a campsite, I found a spare thermostat. I swapped it in, in about one hour, and didn’t lose much coolant. The car runs perfectly fine now. I’ll take it to my mechanic to change the oil and check my work soon.

One friend suggested I find a newer van to go camping in. He doesn’t get it.

While I never got to Baja, this was kind of a perfect Westy adventure. We solved the issues and got home safe. My friend says she’d love to find a closer hot springs and try the VW again. I still want to go to Baja.
