Re: Sticky brakes??

Glad you found the problem .

One other thing, IF all the above tests don't solve the problem, it's the brake flex hose . It would hold light pressure , just enough to make it hard to spin the wheel but not hard enough to heat the disc up like the problem above.

On the front disc brakes for both flex hoses to fail would be rare but with old flex hoses its possible.
This is caused by the inner hose collapsing and holding pressure in the caliper .
To test : open the bleeder at the caliper.

Good news to see that you most likely found the problem.
