Been having trouble wearing out brakes for last 18000 miles. After first premature wear, I replaced replaced master cylinder, then both front hoses/calipers/rotors/hubs with sensors (getting low speed abs activation occasionally as seen elsewhere in this forum). 4k later front worn out again. Took to pep boys and they said the front right caliper was sticking. Had them replace all 4 pads and rotors and warranty the front calipers. Got a 2yr/24k warranty. 3k later front right worn into rotor again. They warranty it, say they have replaced fluid and flushed and bleed system of air.. Tech told me that caliper will release when bleed at caliper and when line cracked at abs valve, but won't release when cracked at master cylinder. Told me to take to dealer, where they could scan abs system and check (no abs/brake/check engine lights are on). He thought it was abs valve holding pressure on right front.
Took to dealer for scan. They told me the Booster and Master Cylinder were not functioning properly (hydraulic air lock??) and recommended both replacement and flush for a cost of $1154 (!!!). Needless to say I went to dealer, paid $120 diagnostic fee and left ASAP. As noted above, master cylinder already replaced (bench bleed before install). Called Pep Boys for price on Master Cylinder ($75) that they had, but would have to order Booster ($100)
any thoughts anybody (roadie)? could the booster do this? Tech at pep boys seemed to think problem was only with right front dragging (which it is definitely doing) and that abs valve was not releasing that particular caliper. Said they had thoroughly flushed the line and both front rubber hoses have already been replaced and there is no line problem.
at whits end basically everything has been replaced (RF pads and rotors 3 times!) except abs valve ($$ and hard to do) and Booster.
