Problems changing EB Rear Brake Pads

beancounter1 · 13-07-2006, 09:53 PM

I am changing the rear brake pads because they are fully worn out. Have removed everything - include the whole rear brake caliper from the car.

The caliper piston will not retract enough to allow me to fit the new brake pads.

I cannot rotate the caliper piston in any direction - it is VERY tight. I do not have the special Ford tool, but I have used multigrips on the outside of the piston and I have tried a flat bladed screwdriver (with little success). Are there any other tricks to the trade apart from buying an expensive tool for one use ?

The caliper is only 12 months old, so I can't be stuffed yet.

It's the right hand side caliper, which I think needs to rotate anti-clockwise to make it retract.

Can the caliper be dismantled, rotated internally with a spanner and re-assembled ?

have you tryed compacting it with a g clamp

You can buy a multi tool cube for turning the piston in, quite cheap and does a range of vehicles. You have possibly burred an edge on the piston with the multigrips so check for that. The piston will be tight, fresh brake fluid is the best thing to lube it with. You may also need to remove the boot seal if you haven't already. You can't diassemble it to wind it back in either.
Good luck

the tool is like 30 bucks.... you just ask for a ea-ed rear brake piston tool at bursons or repbco or similar

it fits inside the piston and has a notch which fits in the little recess that the pad locates in...

if they are as bad as you say they are you need to reco them......dont just try and wind the piston back in......remove it, replace the rubber boot, lube everything up with some fluid then rebuild

when you used the multi grips were you careful not to damage the piston in the are it has to go back into its bore area? didnt for change from that system on my au you just use the old pad and a g-clamp and slowly push it in watching the fluid with lid off.

lol i was to slow already answered.

Compacting the piston with a G Clamp does NOT work on the REAR brake pistons as they only WIND in/out on a thread. I believe that only the FRONT brake can be compressed in.

I have not yet removed the rubber dust bucket. Can this be easily removed and replaced ? I note that the piston is made of very soft aluminium.
