2003 Rav4 Front Disk Caliper

January 22, 2011

Hi all,

Had an issuew with the Rav4 last weekend, the NSF brake seemed to be sticking on our way home from Portsmouth to Plymouth. Had chance to take the front brakes apart this weekend and its seems that the NS caliper piston maybe sticking as the pins are free and move easily.

The disk is also a little more worn on the NS so I'm guessing its been happening for a while.

The pistons on the front calipers seemed a real mare to move, is there something I need to release before I try and push them back in?

Can I get a recon caliper, if so where from?

One last point the disk seems to be held on by the road wheel, is this correct?

Cheers

Sticking caliper pistons seem to be a fault I've found. They can be stripped down and cleaned then rebuilt or just buy a replacement.

The disc is held tight once the wheel is on.

A sticking piston is one of the main reasons why pad material transfers to the disc - excessive heat - and you end up with a so called 'warped disc'.
