Brakes are sticking
Discussion
The front brakes are sticking on my 1990 turbo causing the car to pull to one side. From a search of previous posts I understand that the floating callipers need to be lubricated occaisonally and that this could be the cause of the problem.
How easy is it to check and lube the floating callipers? I'm not sure how to go about it.

Easy.
Remove the front tires.
Take off the pads. remember which side goes where for re-assembly.
Use a wooden or rubber mallot to free the float pin.
Use caliper grease on the float pin and work the pin back and forth.
While the pads are off slightly press the brake pedal to extend the caliper piston so you can get to it behind the rubber boot (But do not extend it too much).
Smear the exposed sides of caliper piston with caliper grease, reset the rubber boot if required, and then use a C-clamp or a quick clamp to squeeze the piston back in to the caliper housing. Do not allow any grease to get on the pads or rotor.
Reinstall the pads in the correct place you removed them or time to reseat the pads will be required for full braking to be restored.
After pads are re-installed pump the brake pedal to set the correct pad clearance before driving off.
On flat level surface test braking power and response at low speeds. Accelerate to 20-25 slightly lift hands from the steering wheel and brake to see if car tracks straight under braking. If it grabs to one side quickly grab the wheel and straighten the car.
Email me if you need more precise or detailed instructions.

Brian,
Be sure to use a silicone grease, this is what 'caliper' grease is. Silicone grease is impervious to water which standard petroleum based greases are not. They (petroleum based greases) will absorb water, form an emulsion and corrode the caliper pin. Hope this helps. Happy Motoring!...Jim'85TE
