Mounted on the firewall near the fender well on the drivers side. The brake master cylinder is what you need to fill.

Jeep brakes


It is very difficult to diagnose this problem with the little bit of information you gave. If the brakes are drum brakes check to see if the brake cylinder is working and has no leaks, lift the rubber seals and make sure there are no leaks there, check the brake adjuster make sure that works okay. If everything works and you bled the brakes properly, then the problem is most likely is the master cylinder or the wheel cylinder.



While bleeding the brakes always make sure you check the master cylinder reservoir to make sure the fluid level is up so you do not get air in the brake lines. When bleeding the brakes did you have someone press down hard on the brake pedal hold the pressure on the brake pedal when opening the bleeder then push the brake pedal to the floor keep it there, until you tightened the bleeder, then pump the brakes up and hold it there, while you repeated the bleeding operation by opening the bleeder when the brake pedal go\'s to the floor keep the pedal down until you tighten the bleeder and then pump the brake pedal back up then check the fluid level in the reservoir, keep doing it until the brake fluid shows no sign of air.



If the brake pedal is pumping up during the bleeding process and you made sure you got all the air out of the brakes and then the pedal go\'s to the floor, make sure the fluid level is correct in the reservoir and the bleeder is closed tight and there are no leaks in the lines, wheel cylinder, brake cylinder the brake adjuster is working and master cylinder, and if you still have no brakes then it must be a defective piston in the wheel or brake cylinder, if there is a seal problem with the pistons you will not get any pressure to push the brake fluid. let me know how you are doing.

Your brakes are vacuum aided so when engine is off the pedal will be hard. When the engine runs the vacuum is active and the pedal becomes light. Your brakes are working but need adjustment so that the pedal does not go to the floor.
Locate the adjusting screws behind the rear wheel drums.
With one wheel jacked adjust the shoes till wheel wont turn.
Then loosen until wheel is just free of any friction from shoes.
Repeat for other side.

It sounds like master cyl. is drawing in air causing prob. also another test would bee too bleed out and get pedal back, now step on pedal and hold firmly and see if pedal creeps near floor indicating innternal leaking in master cyl. also have some one pump bakes slowly aand look for air bubbles in brake res. after bleed out indicating master cyl. is drawing air upon release of pedal.

I can't shift into any gear! I press the clutch Pedal and there is nothing, no response!


First place you need to look is at the clutch master cylinder on the firewall next to the brake MC. Ifg it's empty then re-fill it and s5tart to look for a leak. It is a sealed system exactly like your brake,therefore any fluid loss indicates a leak. Check on the firewall under the master, where the clutch pedal rod goes into the cylinder under the dashboard (inside the car). Check the line to the slave unit and the slave. It helps to have someone pump the clutch pedal to make any leak more obvious. If you find the leak, replace the part that is leaking. If it appears not to be leaking, replace the master as it can internally bypass and not build pressure.
Bleed valve is located on the slave. Bleed as you would a brake.
Some slave units are part of the throwout bearing...if so, to replace it, the transmission needs to be removed. but bleed valve should be on a line right near the pressure line going into the bellhousing.

I am having a problem bleading my 2000 grand pris brakes. check all the brake line no leaks but when i bleed the brabe pedal coes to the floor. i have also bleeb frunt to rear and rear to frunt.


This is a two person job. You have one push the brake pedal to the floor and hold it there. Then the other opens the bleed valve until brake fluid comes out. Close the bleed valve and have the other person release the brake pedal. Repeat. Continue doing this on each brake bleed valve until there is no more air coming out of the lines at each bleed valve just a solid stream of fluid. Fill master reservoir back up with brake fluid as needed through the process. You bleed from farthest to closest meaning from rear to front.

There may be air in the lines. Bleed all your brakes starting at the farthest wheel from the resevoir, and finishing at the closest one. Try the pedal after its bled. If the pedal still feels soft or travels to the floor there may be a pinhole leak that may be spraying on the underbody of the car, or the seals in the master cylinder are gone filling the vacuum booster(if equipped). Air compresses more than oil so if bleeding works that may be the problem.

Brake pedal hits floor with no pressure


if the brake fluid resovoir is full and you havent opened the brake brake system (ie a bleeder screw or removed a brake line) then you probably need a master cylinder. if the brake fluid IS empty then first you must find the leak and repair it before bleeding will do any good.

Brake pedal go almost ot floor before the brakes engage but thers no leak


sounds like u need a new master cylinder - common - they leak within the unit - - the gasket doesn't retain enough break fluid to keep everything working right - also take down the vin number and call the local dealer - ask about any recalls on the brakes or anything else - -also about any service bulletins - - check with more than one dealer if ur not happy with just one - - they make mistakes too
