Hi,

I have been having trouble with my front drivers calliper, every now and again it sticks and holds onto the disc. I have freed the two sliding pins and checked the piston and all are free as a bird. Some one has mentioned to me it may be a fault wit the ABS pump ( but no fault light shows on the dashboard) If the car is left for an hour it seems to free up and can be driven again.
Has anybody come accross this before, any help woulod be greatly appectriated.
