This morning, when I came to drive car out of the garage, I found the handbrake was well stuck. It took 3 attempts, about on the verge of stalling, before it released and for the first couple of brake applications afterwards the brakes were audible in their action.
I put the car away at Saturday lunchtime, after a 40 mile drive in heavy rain, surface water and spray. Today was the first use since.
As I seldom use the brakes they didn't get a chance to dry out, and the pads obviously stuck to the disc. I will try and remember to leave the handbrake off when the car is in the garage. I always leave it in gear anyway.
