Scutch0 Posted July 7, 2014 Share Posted July 7, 2014 My front drivers j spec caliper is binding, I've taken the sliders out cleaned and re greased them, they are now moving freely, however it still seems to be binding? Is it common for the pistons to seize? Any cheap remedy for this too? Quote Link to comment Share on other sites More sharing options...
bignum Posted July 7, 2014 Share Posted July 7, 2014 Swap the caliper, they`re cheap enough these days. Quote Link to comment Share on other sites More sharing options...
stevie_b Posted July 7, 2014 Share Posted July 7, 2014 How do you know it's binding? Is the roadwheel hotter than usual after a drive? Usually if the sliders are moving freely, the brakes don't bind. It's possible that one or both pistons are a bit stuck in the "out" position, in which case either strip the caliper down and rebuild it, or change the caliper as bignum said. If it's just an occasional use car, I would strip and rebuild: if you fit a 2nd hand calioper, unless it's been recently refurbed you don't know how long that one will last.

Dnk Posted July 7, 2014 Share Posted July 7, 2014 Fit new or get properly rebuilt ones. A few places do them and are pretty cheap if you exchange your old units Quote Link to comment Share on other sites More sharing options...

After a short drive there was a terrible smell of brakes, drivers side was considerably hotter than the rest, jacked the car up and I am only able to get the wheel to move using some force. I've had the sliders out, I did notice 2 things, 1) that one was missing an inner rubber (the one attached to the slider), and 2) how much of a pain they are to get the slider back in without damaging the rubber. I've rebuilt caliper a before, so I'm not that daunted by doing it myself, so anyone know where to get a rebuild kit? As the car only does about 2-3000 miles a year. I'm tempted to try and work the pistons in and out to free them off, as they're not leaking or anything. - - - Updated - - - Can anyone point me where to get a replacement caliper?

stevie_b Posted July 7, 2014 Share Posted July 7, 2014 For a rebuild kit, I suggest Chris Wilson or Toyota. Toyota part numbers are in a tech thread on here about it. Quote Link to comment Share on other sites More sharing options...

Scutch0 Posted July 8, 2014 Author Share Posted July 8, 2014 Oh cheers! I have used bigred stuff before so I might try them. Any tips on getting the rubbers on the sliders back in? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted July 8, 2014 Share Posted July 8, 2014 Personally I would leave them out, they are just anti rattle rubbers and tend to promote seizing and just add friction. Quote Link to comment Share on other sites More sharing options...
