Hi Guys,

Fronts are a walk in the park.

Rears, anyone done the rears?

I am thinking that I need to back off the handbrake to get the piston back.

Anyone done the job and have a comment?

There is a fair bit of info here.

Haven't had to replace the rears but have removed them when having a brake problem a while back.

Retract the piston by rotating them - would imagine clockwise to retract. From memory only retract as much as you need to fit the new pads bearing in mind each 1/4 turn is a fair bit. You also need to ensure the cruciform orientation is maintained - there is a locating 'stub' on the rear of the pad squeal shim. The brakes should self adjust with application of the handbrake.

One of my other cars used that system. Gen2 RX7 maybe?

Thanks guys, it all makes sense now.

The repair manual indicates an SST should be used to rotate the piston - see attached. What have others used to rotate the piston? Will any flat plate e.g. a flat file end do the trick?

I just use a broad flat chisel to rotate the piston back in.
Tip: Pump the brakes before you pull the hand brake on. I found the brakes bound if I did it the other way around.

Thanks CB. Did you need to disconnect the handbrake cable at the caliper when changing the rear pads?

Discussed this with CB off-line and have now successfully completed a front and rear pad change. No need to remove the handbrake cable.
