I Have a 95 Accord its a non abs car. heres the prob it used to only be when it was hot out but when i sit at a light and hold the brakes the pedla slowely sinks to the floor. When i let go and push it again i have all kind of brakes then it sinks again. The car is no leaking any brake fluid at all. Any ideas thanks?

 

Brake Master Cylinder

Replace it. And pick up an OEM Honda one vs a rebuilt or offbrand. I believe it's ~$140 in person at the local dealership.

Takes about 20 minutes tops to replace it.
- flare nut wrench
- take off brake lines
- ratchet
- take off two nuts holding it to the booster (SAVE THE WASHERS/NUTS)
- remove
- bench bleed new one
- make sure rubber seal of old one is out
- insert new
- tighen everything
- bleed brakes

done

 

thanks alot i was told it might be that but i figured you guys would no for sure. Ive have a parts car the runs great to would it be worth taking it off that or just buy the new one?

 

The issue is most likely the rubber seals inside the MC, I would skip on trying to salvage a used one that may be damaged itself and just buy a new one. If you're trying to save more money, you could get like a rebuilt one from Advanced Auto but I would suggest going OEM new

 

Thanks alot i really appreciate the help
