Hi

Been searching the site but have not found an answer to my problem.

2015 GDE i30 with 1.6 diesel engine.

Need to fit new rear disk brake pads.  Should be a doddle of a job right?

Got the old pads out and the new pads in.  Can not for the life of me get the caliper piston to retract so the caliper will fit over the new pads.  There must be a new trick here.  Releasing the fluid pressure through the bleeder valve does not work.

Is it something to do with the handbrake mechanism?

Any tips and clues greatly received.

Don't have this model, but caliper compression tool needed perhaps? also if the caliper has a slot and the brake pad has a dimple, then a rotating caliper  compression tool required. Onother cars I have compressed the caliper with the old pads, while still on the car, and/or used c clamp with a block of wood. Make sure your not pushing dirt passed the rubber boot into the piston.

Yep. A clamp should work. But some cars require the piston winding back in.
Someone here should know if that's the case.
Best wait for that info before trying brute force.

I looked into this before my last MOT as I had a clicking sound.
I thought from brakes but turned out to be a bush on the front suspension spring.

Anyway I found the front caliper can be pushed in by using the old pad. Straight forward.

The rear has to be screwed in.
You can buy tool or you can try using a long nose pliers by putting the pointed ends into the 2 holes in the piston to rotate the piston back.
With the long nose pliers method you have to be very very careful not to catch the rubber seal.

I personally would see if you can borrow a tool.

There are vids on the net.

Problem solved.

They are wind back in pistons.  Used a pair of bend circlip pliers and it was easy.

Thank you everyone for your comment and tips.
