You have air in the lines either your brake fluid is really low or work was done on the brake system and air was able to get in. also check all the lines and make sure there is not a leak somewhere this would also allow air into the system. You will need to bleed the brakes to remove the air once you have determined that the system is leak free.

The brakes went to the floor and the light that has the brake with I P on top came on. I filled the master cyclindeer with brake fluid and pumped the brake back up ,but the brakes are soft agian. What can...


IF your brake pedal went to the floor, then you have a brake fluid leak somewhere. Even though you filled the reservoir with brake fluid, the system now has air in it. The first thing you need to do is find the leak and repair it. Most likely a wheel cylinder or caliper piston leaking. Once the repair is done, you will need to bleed the air from the rake system. Since you don't know anything about the brake system, I would strongly suggest having a professional mechanic do the work. If it is not done right, your brakes could fail.

Brake pedal is mushy all the way to the floor. Have already replaced front calipers, master cylinder, and bled all the brakes. Pedal still goes all the way to the floor when stopping the car.


If the car has drum brakes in the rear, Jack the rear up and have someone push the brake pedal hard and you try to turn the wheel. If you can turn it you need to adjust the rear shoes. They may be traveling out so far that the fluid level drops causing the pedal to go to the floor. You must adjust them with the drum on till you hear and feel the shoes rubbing against the drum. Hope this helps.

Theres a noise inside the van that sounds like an air leak down by the brake pedal and it has something to do with the brake system


Yes, the seal in the brake booster has gone bad, leaking vacuum, when it goes out the brake paddle will get very hard and hard to stop your van, the only fix is replacement of power brake booster, hope this was very helpful.

Having trouble with the brakes on my '90 Ford ranger. Replaced the master cylinder and still have very little braking power. Any help would be appreciated!


***Seek out professional help this vehicle is not safe to operate.***


Check the vacuum line going to the brake booster.

This is the big round chamber behind the master cylinder.

Hope this tip helps.

Step on brake paddle with engine off, then with foot on brake paddle start engine, brake paddle should go down a few inches, also check for vacum at power brake booster under hood ( sit in back of master cylindre ) if you have vacum there and brake paddle did not go dnow a few inches, replace brake booster.
