Re: Brake lights sticking in the 'on' position

Howard..I believe I may have solved the mystery of my brake lights sticking in the on position. A while back, I replaced the circular rubber grommet seal on the neck of the screw-in master cylinder fluid reservoir cap. The seal appears to have been just a tad too big, so I seemed to have been getting a tiny bit of fluid leakage from the cap. Also, I believe the oversized seal was causing a loss of pressure integrity in the system. I believe this loss of back pressure was causing the brake piston and pedal NOT to return to the neutral/off position when foot pressure on the brake pedal was removed. With the original rubber seal installed on the neck of the reservoir cap, no leakage or 'sticking' of the brake lights is occurring. PS..this original circular rubber grommet/seal on the neck of the reservoir cap is a bit checked and worn. Do you know where I can get another one of these, or should I just go to the hardware store and try for a closer match? Thanks again for all your help and suggestions.
