I recently did my rear pads but the rear left keeps "scratching". I pushed the piston all the way in and it was pretty easy to do so. What could be the problem?

 

do you have all the bolts torque to spec? did you replace the rotor also?

 

Did you push or turn the piston in? If you pushed it in and it was easy that doesnt necessarily mean you won't have a frozen caliper. The way you adjust the position of the piston is by screwing it in or out (rightie tightie, leftie loosie...as usual). Take the caliper back off and screw the piston in just until when you put it back on, the wheel can turn relatively freely, but not so much that you can wiggle the pads in their place when everything's all back together...worst case scenario you screw it in too much and it'll take a couple of miles to adjust itself properly.

 

no i didnt torque to spec i just screwed it back on as hard as it'd go.

I twisted the piston in, not push, I dont think it'll go in that way.

I dont quite get this. Thanks for the replies.

 

yeah it doesnt go in when you try to push, tried that b4 for like 15 mins. felt like an idiot. He meant that have the piston little bit out so the pad wouldnt have any play when the caliper is installed back on.

 

It is possible to push the piston in with a C clamp, thats how ive always done it but anyway...There should be a slight drag between the rotor and the pads, but not too much that it is hard to turn the wheel. Also are there separate pads for the parking brake in the rear(should be like drum brakes)? If so those are supposed to drag as they are usually self adjusting.

 

did you mess with the parking brake at all?

 

Also, what you could or may have done... not likely, but is possible to happen..
Would you have used your hand to prop yourself on that dust shield behind the rotor without thinking about it throughout this process? That dust guard is a piece of fuck... I accidentally bent one into mine when I was working on my clutch.. just check and make sure there's no contact on that thing....
I'm not positive, but i'm pretty sure it's safe to just take those ugly ass dust shields off, if you want.
Maybe someone could back me up in the thought that those shields don't serve much a purpose?

 

you could take the dust shields off, i guess, but that would mean that as well as getting brake dust all over your wheels, you'd be getting it all over the parts on the other side of the brakes, like suspension, bushings, and in the front, the axles. I'd keep em on, simply for that reason, but i don't really see it as being such a bad thing if they were gone, aside from the brake dust everywhere thing...

 

my wheels are always covered in brake dust anyways... I think if you at least give your car a bi-weekly rinse down, it'd be ok..
