Seized caliper...
« on: July 04, 2012, 11:53:51 am »
Hi guys...

I had a seized r/o/s caliper which I replaced two weeks ago...

But a week later my f/n/s caliper seized...

This front caliper seizes and Un seizes when it feels like it...it's ok for a few days then it's seized then ok etc...

Any ideas what could be the fault here... ???

I had this on my 172 cup once, turned out that although the caliper was seizing, it was a slightly warped disc getting hot and in turn transferring the heat to the caliper which expanded and seized, that was causing the issue. Ordered up some caliper seals and a new piston along with new discs and pads and its still going in the hands of my friend to this day :)

Is it just after a drive that its seizing?

A faulty brake master cylinder wouldnt make just one caliper seize I would have thought. Only issue with a master cylinder I've ever had has been a leaking one, with the pedal slowly going to the floor. Sounds quite strange

My pedal did go to the ground a few times but it's ok now

sounds like air in the system following the caliper replacement.
