So thought I'd share a very odd failure in the rear brakes. We were on the Whipsaw trail... don't remember where the failure could have happened... but after I climbed this:
I hit the brakes... and they were extremely soft... and went to the floor. So I jammed under the truck like this
and found the right rear to be leaking brake fluid pretty badly out of the drum. When you're that far out of civilization, no point in pulling the wheel off and checking things. I cut the hard line with a set of side cutters... which stopped the leak.... folded over the brake line and pinched it off with a set of vise grips. Then strapped the vise grip to the axle. We topped up the brake fluid which thank goodness didn't totally empty out, so there was no air in the system. Brake pedal was firm... held pressure etc... so we continued on with 3-wheel brakes... being very careful on all decents and planning escape routes while driving at all times.
Another pic of working on the truck and some of the group brainstorming with me
When I got home and pulled the right side apart, I found the brake shoe to have collapsed... like a weld broke or something... then causing the wheel cylinder to pop apart and leak fluid. So I replaced both side shoes, cylinders and spring kit... and it's all back to normal now, but no idea what caused the failure.
The collapsed shoe, sorry, camera phone pics:
A good shoe to compare
And a random photo for you
The shoes got warrantied... but the rep stood there like I failed to tell him how I abused the truck to cause this... sorry man, being 39 and with the kids in the back while exploring, I drive safely and smoothly... but he still doubted me... bugger.
Odd failure... I think it was a manufacturing issue with the welding at that spot.
