I own a 1987 Prelude SI. I have ran into some sort of problem with my brakes. When I first bought the car everything was normal. One night on the way home my driver side caliper locked up. No big deal. I went to O'Reily, bought a new caliper, beld my brakes and i was on my way. Two days later I lost pedal feel. My pedal wouls sink at stop signs and it was really soft. So I look over the car and find a bad rubber hose on the right side. Same process and I go off again. Well that night, same soft pedal. I replaced the master cylinder next becaus it was leaking. Ever since then i cannot get a firm pedal. I have returned the master cylinder 3 times, replaced both front calipers, new pads all around, new front rotors and have beld the brakes per my manual. I also bench bled each master cylinder before I put them on. When I bleed teh brakes i get a pedal for about 10 stops. Then I get a soft pedal again. I am all out of ideas. I have never had a car with a brake problem like this. I would love some ideas, answers, or whatever you have . Lucky i have a company truck now so it is not a DD.

Cliff notes: Crazy brake problem. All new parts and soft pedal no matter how brakes are bled.

 

All that is left is the brake booster. They cost about $100 for a rebuilt.

Usually the brake booster would give me the opposite. I bought a prop valve today so I will change that and I am going to go over the entire underside of my car to look at all the lines and fittings. I will check the brake booster when I start to work on the car again. Hell at this point I might as well. Nothing has been as it should here lately.
