Pad replacement with handbrake on

[Rich]

Hi all,

This arvo I was bleeding my rear brakes when my assistant pull ON the handbrake (she thought it should be on for safety). I wasn't aware this had happened when I decided to replace my rear pads while I had the wheels off. As I had to use a clamp to force the caliper piston back, would this have somehow damaged anything? I would've expected the calipers to be difficult if not impossible to remove with the handbrake on but they slid right off like normal.

I went through the bleeding procedure again after I found the handbrake on so I'm not too concerned from that perspective.

Haven't driven the car yet as I thought better to check here first.

Sorry, should also add it's a CU2.

FYI the rear pistons are screw type - you cannot compress them so to speak. You wind them back in with a tool or large flat chisel sized device. If you compressed them back in I worry you might of damaged the piston bore

That's exactly what I was expecting to see. I've done rear brakes before on other cars but this was just a hollow piston like the fronts - no notch to insert. Think it might be different on the CU2 to CL9 and certainly different to the American versions I watched on youtube. The pads had 3 backing springs that inserted right into the piston but there was no notch or crosshairs to use for turning.

Any pictures or links for everyone's info ?

I'd already put the wheels back on and lowered the car before I realised it might be a problem. I've just called a Honda specialist on the off chance they'd answer (public holiday) and they did... Apparently the handbrake is separate and the piston is just a push in with no screw mechanism so no damage done.

Thanks for your replies Bennjamin.

Great to see you worked it out. If you can find a picture on google and link it here that would be great for future reference !

Okay best I could do is the attached pad image. Searched o Google but nothing. All rear pads I've seen in the past have notches that slot into the cross pattern on the piston. My 2009 CU2 rear piston looks identical to a front brake piston. The springs on the pad backing insert into the piston cavity.

They should have charged you for it
