the brake lines needs the air that's trapped in the lines bled out. it's a 2 person job. typically, if u didnt take the caliper off, u shouldnt need to bleed the brakes, but if u did take a brake line off, the brakes will need to be bled.
make sure the master cylinder is full of brake fluid. u'll find a nipple on the caliper. some1 needs to pump the brakes until they start to stiffen up, then hold the pedal. open the nipple slightly. when some fluid comes out, the pedal will go to the floor. hold it to the floor while u retighten the nipple, then repeat.
u'll need to do this until the brakes are back to normal. do not start the engine to do this or u will wind up pressurizing the system.

Did it do this before you did the brakes? I will make my answer in 2 parts.
1. If it did this before hand you can do a couple simple checks. First with the engine running push the pedal down one time. Note how far it goes. Next pump it about 5 times and not how far again. If they are the same then it is most likely not air in your brakes. This could be your master cylinder. If the brake pedal gets better then it is most likely air in your brake lines which will need to be bled.
2. If this happened after your new brakes, what all did you replace, calipers, hoses, etc.? You didn't say you did so I will assume you didn't. Changing pads only will not introduce air in your brakes. Did you resurface your brake rotors or replace them? If you didn't that is your problem. A flat pad "new" pushing on a rotor that is not flat "not resurfaced" Will not give you 100% contact. If the rotors are bad enough you can notice it in answer 1. Otherwise you have to drive it and when braking it the pedal will go down farther to stop. Over time the pad will wear to the shape of the rotor. If the rotors were resurfaced then you may need a master cylinder. This happens when people don't open the bleeder valve when compressing the piston back in which is a big no-no if you have ABS.

If your brake (not break) pedal goes (not goose) in too far, it sounds like you either have something out of adjustment, or air in the lines. Adjust the rear brakes until they hold, then back off until they are just loose. The front pads are self adjusting if you did it right.
If that doesn't help, take it in for a brake bleeding.

If the pedal won't pump up and stay there, you'll need to bleed the brakes of trapped air in the hydraulic lines. This assumes that the rear brakes are adjusted up to contact the drums.

The symptoms described indicate there is air in the brake line. The air needs to be removed. Air is compressible whereas the hydraulic brake fluid is not. Therefore the air needs to be bled from the line. A procedure to do so should be available within the brake installation instructions.

regrettably in the experience that your rotors are undesirable then new brake pads won't help you in any way. How do you comprehend that the rotors are shot? there's a minimum thickness to rotors and finding on the make and kind of the vehicle in question you're able to easily have them became (floor flat) maximum shops won't fee plenty for this technique. I had mine completed for 8 money slightly. I bumped off them myself and took them in. i in my opinion propose against merely changing the pads. if the rotor is warped or relatively is merely too worn down then you definately would be spending alot extra interior the long-term as nicely as putting your self in a risky situation. desire this helps. merely examine your rotors first they might desire to nevertheless be good.

You have to manually adjust the new shoes in the drum after you replace them. You do it through a little hole in the side of the drum.

you probably need to bleed them out real good air has gotten in the system,and that's probably whats causing this to happen,,if that don't help it you may need a new master cylinder for it,,and be sure to adjust the back brakes up to where there's not much slack in them,this will help give you some pedal back on it,but if you bleed them off ,and that don't help,you may need to replace the master cylinder right away,,good luck with it,hope this help,s.,happy new years.Source(s): been a certified mechanic for 36 yrs.
