On my daughters '06 Mazda3i(2.0L) rear caliper piston seal/boot is torn causing moisture to get in past the seal and the piston to NOT Retract.
The caliper/piston IS NOT FROZEN/SEIZED as, with a little elbow grease, I have freed it up by turning in the piston(turn in, not pushed in piston)...
*This car uses the disk brakes as the parking brakes and does not have P-Brake shoes under the rotor hat.
That being said, when turning in the caliper piston(while freeing up the stuck piston), the seal/boot has torn even more in the process and I would like to replace it
I want to replace the seal and I have found this at AAP, part #15293 at the top of the page:
http://shop.advanceautoparts.com/p/econo...ents#fragment-1
Right now(after freeing up the piston), it is reacting as it should and is not hanging. But, with foul weather approaching, I want to replace the seal/boot to eliminate the contamination(rain/dirt/road salt) that will cause the piston to finally seize for good & locking the driver side rear brake against the rotor.
Prior to this, the brakes pads were only holding on mildly after the brake pedal was released but, not causing full lockup and the wheel could still be turned by hand(after releases of the brake pedal) though, I could feel the total lack of freedom compared to the other side!(DID I SAY THIS RIGHT?)
My question is:
Do I have to remove the caliper(from the car) and remove the complete piston(itself) to install the new seal/boot? I didn't buy this seal/boot yet and I just want to make sure it's a quick install.
And questions you may have that I did not explain well/correctly, please ask.
Thanks In Advance,
CB
