Title: Seized caliper...
Post by: GTi E30 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?

It seizing when ever it feels like ur really some times it's ok for days but since the last two days it's been seized...
Someone said the brake master cylinder is Nackered ...??? Could that be the problem...???

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.
