If your car has drum style brakes on the rear make sure they are in good shape and adjusted up, some self adjusters hang up and let your shoes wear down to where they have to move so far that it takes alot of foot pedal to get them to work...

Hi Susan, rich has it all just about right but I suggest you use a clear jar half full of clean new fluid, a piece of old vac, or fish tank hose that fits over the bleeder and the other end goes in the jar submerged all the time Then bleed as normal. When you see no more bubbles in the jar just fluid it is bleed close and move to the next. OH You start with the wheel farthest from master cly. 1st so its correct order would be RR-LR-RF- LF he just has it backwards. This way your sure you have all the air out and system has no leaks.

Hello Susan,
You will have to have the brakes (especially the front ones) bled continuously until the air that is trapped in the lines comes out!
Brake systems use about 2/3 of the available braking power sent to the front wheels and that is why the front ones must be fully bled before you will notice any changes in the stopping /brake pedal feel.
Start with the wheel closest to the master cylinder and work your way around the vehicle. Front left, front right, rear left, then finally if needed the rear right.
Good luck!

    Actually you are supposed to start with the wheel farthest from the master cylinder. Normally if you replace the master cylinder you are supposed to bench bleed it, that will help keep from introducing air into the system. Now if you didn't do that you pumped air into the rest of the lines. If you buy a cheap vacuum bleeder from Harbor Freight, you can open up the bleeder and pull the fluid through. This way captures the fluid coming out and can be put back into the master cylinder, so you don't waste so much fluid. Plus saves a lot of mess. Good Luck!

SOURCE: New master cylinder and booster. Brakes stop good

Well if you have bled it correctly starting at the farthest out(PS Side Rear) and working to the closest(DR Side Front) and you make sure to close the bleeder valve before letting up and repumping the peddel,then I would say that the seals in your new master cylinder may be bad.When you bled the second or third time if there was no air then I would say you have a bad master cylinder.If there was air then you have another problem.Well hope this helps and good luck.

You need to check wheel cylinders, the only way that the brake peddle will go to the floor like that is if there is a lose of fluid pressure somewhere .

Have no brake pressure, pedal goes straight to floor, put on new calipers and pads and bled the lines but I am no better off.


Sounds like a bad brake booster. To test, pump up the brakes with the engine off. While holding the brake pedal down,start the car. The brake pedal should drop a couple of inches and hold. If it doesn't, replace the booster.

If you hear air, it is probably a failed diaphram in your booster. When you say you had good pedal, that was with engine off, right. Then, with engine on it goes to the floor. Does it still go to the floor with engine off? If no, it is the booster. Let me know if this isn't it or you have more questions.

When you bleed the brakes are you starting with brake furthest from the master cylinder? Also was the master cylinder bench bled? If everything there is okay and you are not getting any air in fluid stream, you could try bleeding the brakes by having some one slowly pump the pedal till it is firm. Then have them let off open first bleeder valve and slowly depress to floor and hold there untol the valve is closed. repeat this at all bleeders. You may want to have car running to do this. Try this and let me know.

you need to use a pressure system to add fluid into the master cylinder and then bleed it.
