A year 1/2 ago my wife’s car (2008 Mazda Tribute) started acting funny.
The brakes started squeaking while driving, but as soon as the brakes were applied, the noise stopped. They also had a mild grinding sound. Not a metal on metal (aka no brake pads)…very superficial. Had to slam on the brakes and it activated the ABS (light did not come on) which caused the brakes to go to the floor.
Brought it in to the mechanic we always bring it to. They changed the pads and resurfaced the rotors. I KNOW they bought the cheapest aftermarket pads. I’m sure that and because the pads weren’t deglazed (I’m assuming they didn’t) is what is causing the noise.
Well…brakes worked fine.
Months later had to slam on the brakes again. Again, ABS activated (no light came on), brakes went to the floor. A day later it was still going to the floor.
Brought it back to the mechanic. They said nothing was wrong with the brakes, but they resurfaced the rotors. Brakes back to normal.
Happened again. Noises still there. Rotors resurfaced. I asked if the cheap aftermarket pads could be the problem. Of course the shop said no.
Brakes went back to normal.
Well, it happened again. Had to get on the brakes. and now they are almost going to the floor.
Brought it to a shop and they bled the brakes (not sure if they pulled the ABS fuse or not).
Brakes are still spongy and go down far, but not as bad.
Doesn’t appear to be the brake booster (put foot on brake while car is off and brakes depress when car is started).
Brought it to another mechanic (thinking it was the master cylinder) and he says he doesn’t think it’s the master cylinder, but an ABS problem.
Any ideas? I’m at wit’s end.
