Can anyone who has replaced their rear disc brake pads answer a question for me...To push the piston back into the caliper will a C-clamp work (as it does on the front calipers) or does it have to be screwed in? The shop manual shows a special tool (SST) but it isn't clear if the tool pushing or twisting. Thanks.

 

It'sa pushAND twisting motion.
And if anybody can explain to me why auto companies are doingbrakes this way these days, please do, 'cause it makes absolutely no sense to me.

 

Thanks Virgin1. I had two Saturns and an Oldsmobile that were the same way.

 

Oh I know this has been going on for a while...probably since the early '90's. I just haven't found anyone that canexplain the reason why they have a piston that has to be twisted in w/a special tool instead of just being pressed in. It seems silly to me.

And you're quite welcome, Clem. Welcome aboard.

 

I'm not at all sure why it affects it, but I'm pretty sure it has to do with the e-brake. It depends on how the e-brake works on the caliper as to whether is is a press-in or screw-in. I may be completely off base but the head mechanic at my shop explained the difference to me once and i think it was related to. Not having rear disc myself at the time the knowledge has since escaped me... This may not have helped at all... my apologies. haha.
