Sticking brakes

tuborg_man

I've a 2009 chevrolet epica diesel that is suffering from a sticking brakes on the drivers front wheel,
The brakes start to stick after they heat up. It is used aas a taxi so there's a lot of stop start driving along with quick blasts down motorways etc.
The sliders have copper greece on them and seemto be working fine,
What else should I be looking at to fix the problem,
The brake fluid was changed after christmas, would I benifit from new pads despite there being meet left on the current pads, could it be something to do with the servo or is it a caliper rebuild,
Thanks for reading.

How do you know brakes are sticking? Wheel hot to touch? Squeals?
Have you checked the brake hoses? Bedded brakes?
Any judder in brake pedal? Pulling to side?

My bet is that the rubber boot on the caliper piston has a small hole in it and is letting dirt in and jamming the piston with crud. usually the psiton starts to rust if the boot fails. I wouldnt go changing the boot, as they are hard to find in the right size and near impossible to fit to a caliper that hasnt been cleaned in a acid dip.

You should go to your auto factor to see if they can get you a reconditioned caliper. or a breakers yard for one maybe.

i have an 08 Epica & had the same problem with my rear brakes. A new set of pads fixed it for me. The old pads were not totally gone either.

Almost always when replacing pads the slide pins/guides are lubricated and this will help with the sticking.
The vid I posted show another issue, not as common, where the brake hose deteriorates inside and causes the brake fluid not to be able to retract as easily and causing the pads to stay pushed against the rotor. The vid also show how to determine if this is the issue.
New hose is about 20 euro give or take.

Cheers for all the help, after having a route around it was a slightly warped disc that was getting worse when warm, so hopefully after the weekend i'll get the new disks and pads fitted, (once I get the disc's, motor factor has being having trouble getting the right size and the online places don't stock the correct disk)

You can get the correct discs on ebay. Use parcel motel for delivery & only pay uk delivery charge.
