So I am changing the rear disk breaks on my 94 mustang. And When you take off the pads there is that pisston that you need to puss back in. Well I've tried everything to put it back in. I tried to just push it in with a C clamp, I've tried twisting it(not very much..I was burned out after all the other stuff) but I called around and they said to twist it while your pushing it in. My question is how?? There are a couple groves in the face of thew piston but I don't have anything that would fit them and twist at the same time. Any sugestions will help. Thanks TOM
Tom, you need a special tool. Either get it at your Ford dealer or at Sears. Here's a link so you know what your looking for: http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&vertical=TOOL&pid=00946344000
Well I didn't get that tool and still got it back in. All I did was you a pair of pliers and grab the notches and twist it in. Then put the break pads on and then the disk(I think is what its called, the thing that the pads squeese) and finally screwed it back on. I might get one of those tools for next time but I do n't know yet. Thanks Tom
The only problem with doin it with pliers or channel locks(which I am guilty of) is that the piston get's messed up. The piston is then more likely to sieze in the bore and most of the time you will also tear up the rubber boot when doing it with pliers. Then water gets in and rusts out your brakes - and that's not good.
If you have a beater pair of needle-nose pliers, you can also do it without the special tool. Like others said though, be careful not to damage the piston or the rubber boot!
