UK Brake Caliper - rewinding Pistons advice


Sheefa

Recommended Posts

Hi all

 

I've now removed my brake discs and pads ready for the new ones.

 

I had purchased a brake Caliper piston rewind tool but it's far to big I think to access the Pistons and given I'm not going to split the Calipers in half how on earth do you push the Pistons back in? Assume I need to open up the cap on master brake cylinder to release some pressure?

 

Help.

 

Thanks

Greg

Ok so that didn't quite go to plan.....

 

Unfortunately as you can see one of the piston rubber seals is quite badly corroded. The brakes were working fine but obviously this has to be replaced. I've been speaking to Glanza_Mike who's going to help me out if we can rebuild with seals etc. However, is there any way to get the Pistons out without an airline as per enclosed page from manual?

Thanks

How many pumpkins do you reckon we'll need mate?

 

:D

 

Hahaha. Oops. I've got plenty though.

 

I've done this a number of times and you will need at least two pumpkins, three to be on the safe side. Be careful not to get the seeds behind the pistons though :D sorry couldn't resist hope you get it sorted

 

Get out you :)

 

If the fronts are that bad i'd have a close look at the rears too ;)

 

Yes Dunk I know. Got new discs and pads so will be fitting, looks like this will be a bigger job than first thought ! Cheers.

 

Sounds like it's going to be a messy job mate :p

 

It is. Get ready!
