Hi guys,

Newbie here, with an easy question. I understand that the piston in the caliper on the rear brakes rotates to retract during a pad change. That pin on the pad is strange though. If the pin locks into the cut-out or slot...then it seems as though the piston can't rotate as it comes back out? Does it move out without rotating?

Thanks, Ross

 

not sure, but i belive the piston does NOT rotate during normal brake operation, only when a special tool is used to manually retract it for a pad change.

 

I know that AutoZone will loan that tool for you for free if you leave them a deposit.

I have a shop and never needed to borrow tools before but the other day I boke my P/S puller and they loaned me one until I went to Sears to get a replacement.

 

just buy it at harborfreight. they have a set for less than $20.00. dont be a cheapo and use a big channel lock to rotate it.

 

Back to the question....does it rotate out or come out straight?

 

It comes straight out, rotates only to retract.

 

OK cool...thanks guys...I guess that explains it.
