Hi. Happy New Year!
My front off side wheel has intermittently become very hot with a burning smell. The caliper (4 pot ) was rebuilt with new pistons and seals when the pads were changed in July.
It takes more than 20 mins driving for this to happen, and is noisy at 50/60 mph.
I had the wheel off, and the pads came out easily, and there was no bearing play in the wheel.
It happened again on my next longer journey, and so I dropped into the (nearby) garage that rebuilt the pistons; like me, they couldn't find any issues, the pistons moved freely, and it drove fine afterwards, but I didn't push it.
Braking is fine, no pulling.
Any suggestions ? Many thanks

 

There is sti a possible issue with caliper as we ve had this couple of times
Possible brake flexible failing
Is it running abs??

 

Its an 05 wagon, with abs.
Brake flexible?
Thanks for replying

 

Hi
It can still be a caliper issue even after changing the Pistons , as well as the standard Pistons rusting , the top lip inside the caliper bore also rusts , the inside bore of the caliper needs thoroughly cleaning , all rust needs to be removed , if not you have the issue you're now having.
The calipers need to be stripped again and cleaned out properly , if done properly they will be trouble free
