One side done other is disassembled what a job
Right side (passenger)was the side where the pad had worn down to the back plate. Took almost an hour to get the damn thing off after unbolting both the caliper slide pins and the bolts holding on the caliper bracket which retains the pads. The 15mm bolts had to be unscewed 1/12 trun at time with a combination wrench as they were blue locktited on. Removing the caliper slide pins didn't allow the caliper to come off even though it should have.
With all 4 bolts off used a pry bar to goose the caliper and bracket off of the rotor. Then removed rotor and reattached caliper just enough to use a cube to rotate the caliper piston in. Clockwise didn't work, Counterclockwise did. Not sure what direction I need to use in the left(driver) side.
Rermoved slide pins and noted the one near the BOSCH logo on the pad retaining piece has a fluted rubber sleve near the end of the pin, The other pin does not and has a side that is ground flat. Used brake cleaner and dried before relubricating with caliper grease.
Assembly was OK except the pads kept falling out of the retaining clips. Did NOT lubricate them as they were a mess to get on without getting brake grease on them. Backing has nitrile rubber in addition to the steel plate which is on the back of the pad. That should be enough. Used original hardware after cleaning with break clean as they were not rusted and had pleanty of spring in them.
I did NOT remove the e-brake cable or hydraulic lines as it seemed unnecessary.
Got drivers side off and was trying to reseat the caliper piston but it got dark so I will go for this tomorrow.
Thanks for the detailed instructions and suggestions.
These brakes were a challenge and are not the easiest ones to replace.
