Here's the deal on my daily driver bucket of rust, which someone was too lazy to do the work on so they just gave it to me... 89' Honda Civic 4d LX 1.5L(Front discs/Rear drums)

Brakes had no pressure and I had to press to the floor board to stop. Got a free brake inspection so I didn't have to play the guessing game and also not have to pay the shop $405 to replace the master cylinder, rear drums and to do a fluid flush. I replaced the master cylinder(which was leaking where it connected to the booster) and the brake booster(terribly rusty and looked like it was going to break apart into a pile of rusty dust at any moment). Bled the lines after that. Got a few miles down the road this morning and the brakes were sticking more and more until the car wouldn't move and I could barely press the brake pedal in. I had to release the pressure by loosening the bleeders just to get it back home. I could tell they were slowly getting worse on the way home with each press of the pedal due to the pedal movement decreasing and the car struggling to accelerate in any gear. Any ideas what would cause this?? Appreciate the help! Thanks

Master cylinder or booster is not adjusted properly. The pushrod is pressing down on the piston of the master cylinder so fluid cannot travel back to the reservoir when the system heats up.

 

That would make perfect sense! The small metal connector that connects the pushrod to the pedal is on the very edge of the pushrod to allow the pedal to hit the sensor that turns off the brake lights, so I'm convinced you're right. I'm going to adjust it either today or tomorrow and then I'll post my results. Thank you!!!

 

Adjusted the push rod on the booster and that corrected the problem. Thanks again.
