Got my car out from its winter slumber, and have a few issues with the brakes...
1. The red BRAKE light illuminates every time I push the pedal down, but goes out. I've done a lot of reading in this thread, stating the accumulator ball is the likely suspect. I had this issue about 4 years ago, and the culprit was the pressure switch on the back of the master cylinder. I had a NIB switch, so for giggles I installed it, but the problem is still present.
2. Since I replaced the switch, when the brakes are applied, I hear a knocking type noise from the firewall area and can feel it through the brake pedal with my foot on the brake. After I take my foot off the brake, the noise will continue 2-3 times then stop until the brakes are applied again. Could this be also related to the accumulator?
The brakes seem to stop the car well without concern, but I'm a little put off now with this new knocking issue from the firewall. I have been previously contemplating a vacuum brake conversion based on the overall costs, but before I pull that trigger I would like to get the thoughts of the Powermaster experts.
Thanks!
