My build thread is pretty jumbled. I'm so far behind in updating it on major parts of the mechanical refresh and the pop top. But instead, I have this post where I'm not even building, I'm just breaking things.
Coming back from ol' Mexico, my brakes gave me some excitement. I was slowing for a checkpoint when I heard a bit of a grinding sound. Fluid levels were ok. One wheel hub was a little warm to the touch but not hot. It was stopping fine. I attributed the noise to a rock or something wedged around the rotor and resolved to check it a couple more times as I made my way north.
The sound didn't return and the fluid levels were ok and I was braking evenly so I kept going. Then at a stoplight near the border, about 60 miles and 4000' of elevation gain from my campsite for the night, a billowing cloud of vaporizing/burning brake fluid came tumbling out of the left front corner. I topped off the fluid and decided to limp back to town where I had a friend who'd let me use his garage. I was ready to clamp that corner if it leaked too bad but was hoping not to damage the brake lines.
In town I ordered a caliper and pads from Autozone. I usually would go for a local shop but the minions of our corporate parts store overlords were open late and swore they could get them to me the next day. That didn't happen.
While I waited, I took the wheel off and found one of the caliper bolts had come loose. I don't usually put lock-tite on my caliper bolts to make it easier to service them in the field. But this is the first time I've had one back out on me. One was missing and one was loose. Just enough for the caliper to wedge itself up against the rotor at an unfortunate angle. The other caliper was fine. We modified an m12 bolt with almost the right shoulder to fit, along with a small washer stack, and secured the caliper. It was a greasy mess and I doubted the seals were any good.
It didn't matter though as the parts never arrived. Eventually I got a refund and got back on the road. I didn't have to use the brakes much, and when i did I just pulled over and topped off the reservoir. Descending the mountains from Tecate was a bit of fun with minimal braking but I made it. To the troopy's credit, I never once lost brake pressure or failed to stop at a reasonable distance.
Once in the states, I did get a new caliper, installing it in
@repentsinner 's driveway.
I didn't even make a mess
My rotor's are pretty hosed, as are the pads in that corner. And I should probably flush all the fluid as well.
In the end, a quick 1 beer job
As for brake upgrades, I decided that I want to keep to this tire size and this wheel size. That leaves the Tundra brake mod, which will clear 16" wheels, but requires different hubs up front and 1" spacers in the rear. I'm a bit allergic to spacers, so rather than jump on that, I'm going to:
- Install either an 80 booster w/@cruisermatt 's clevis mod or a 70 booster
- Turn or replace the front rotors
- Replace front pads
- Install a fresh LSPV to the rear
If this doesn't square me away, I'll reconsider the Tundra brake mod or going wild with 17" rims and the bigger 4runner brakes.
Excellent info on brake upgrades in this thread.
On the plus side, this misadventure lead me to meet my friend's neighbors for friendsgiving. they have built themselves a little slice of desert racing heaven with a full shop, bar, kitchen, karaoke, stripper pole (mainly used by fully dressed middle aged men but hey it's the spirit that counts), and plenty of taxidermy. They were welcoming and gracious hosts and I had fun.
Somebody's havin' a good time
