Hello everyone, I am having a problem with my 2005 Honda Civic's brakes. About a month ago I pressed the brake pedal and the car wasn't stopping, so I released the pedal and pressed it again and the brakes worked fine. I wasn't sure what happened, so I drove very carefully in case it happened again and I was ready to downshift and use the emergency brake to stop if I had to. The brakes felt perfectly fine for several weeks after that happened until yesterday when the same thing happened again. I hit the brake and the car wasn't slowing down, if I remember correctly I released it and pressed it again, still nothing, but it worked fine the 3rd time and has been working fine ever since. When the brakes fail the pedal still feels firm, if anything maybe a little firmer than normal, it didn't go tho the floor.
Here's a list of the changes I made to the brake system:
Rear disc brakes from Civic SI
Proportioning valve for rear discs from the same Civic SI
Steel braided brake lines
Hawk HPS pads front and rear
Other than that the brake system is stock (no ABS). I am thinking after 254K miles the master cylinder may be going out, but I would think that a bad master cylinder would be consistent, it's weird that the problem would be this intermittent. Could the proportioning valve possibly do this?
Thank you very much in advance, I really appreciate your help
