I have hardle any pedal. I have replace both back shoes as well as front pads. If, you pump the brake pedal 3 or 4 times it will built up a little bit, but no much. I have removed the check valve a plugged off the vacumn and also plugged the hole that goes into the booster and the pedal was real hard then.

First off, the master booster needs the vacuum line to work, so your problem is the booster needs replacing.

I have a 23 t bucket and i cant get a brake pedal.when i bought it had very little brake so i replaced rear shoes and cylinders,front pads and calipers,all new lines and the master cylinder


Once you have bled the air from the brake lines,clamp off the front brake hoses carefully.Does the pedal feel better now?
Then the pad /caliper fit is allowing too much play.Is the pedal the same?Then clamp the rear hose and try the pedal.Is it fine with the rear hose clamped?If so we now know the problem is at the rear brakes.One common low pedal rear brake cause is brake shoes that do not fit the drums.Remove the drums and look at the shoes,are they showing contact wear fully or just in the middle of the shoe?Remove a shoe and place it in the drum.Can you rock the shoe against the drum surface?Once drums have been resurfaced,the shoes will not fit fully against the drum allowing the shoe the flex when applying pressure to it and this can easily create a low soft brake pedal. Of course rear brake adjustment must be correct once brake shoe contact is correct.To correct brake shoe contact,have your shoes re arc-ed to fit resurfaced drums or install new drums.Don't overlook brake master cyl /brake pedal push rod adjustment too.

Brake peddle is low,


Pedal, not peddle. First make sure reservoir is full at the brake master cylinder. Then check your brake pads (for disc brakes) and/or brake shoes (for drum brakes). When the pads or shoes are very worn down, you will get a low pedal. If you have disc brakes on the front and drums on the rear wheels, first try just replacing the front brake pads. If you get a good pedal after the front is done, many people tend to let the rear brake shoes go unless they are making noise. These systems are designed to put most of the braking force on the front discs, so the rear shoes do not need changing as often.

Brake pedal


Did you ensure that the master brake cylinder was topped up properly whilst you bled the back brake shoes?

If you did so and the brakes are free of air in the lines, then you still have to adjust the brake shoes to their operating position. Secure vehicle from movement. Jack back wheels of the ground, support with jack stands. Remove the rubber grommets that covers brake adjustment wheels. Turn star wheel adjuster with special adjustment tool or a wide blade screw driver. Lock the wheels with the adjustments, push in brake pedal until you have pressure, back off adjustments until wheel runs freely. you should have plenty of pedal now. Make sure master is at the right level at all times.

If you don't have pedal now then I would suggest you still have air in the brake lines.. If you pump the brakes until you have pressure and the pedal feels spongy , then you still have air in the line somewhere. Bleed until air is removed.

I put new brakes in my saturn. i put new front calipers,rotors and pads and power bleed front only. i also put new brake pads in rear but did not replace drums.after all that i can't get a hard brake...


try adjusting the rear brake shoes but.....spin the rear wheels first is u get the feeling of the shoes grabbing then releasing ( the tire gets loose then tight as u rotate it) u will need to have the drums cut on a brake lathe or replaced...when u have this done , then adjust the rear shoes until u get a slight drag on the rear wheels..go pump the brake pedal to seat the shoes if the wheel spins free adjust the shoes more an repeat until they have a slight drag after pumping the brake pedal

Put new shoes pads and wheel clyniders on truck had air in the lins gravity bleed brake and still can not get a full pedal


First make sure the rear shoes are properly adjusted. Then try pumping the brake pedal a couple of times and see if it gives you full pedal. If it doesn't then get a helper and pump the brake 2-3 times and then open the bleeder screw. When the pedal sinks to the floor close the bleeder screw BEFORE you let the pedal return to up. Repeat this on each wheel, starting at the farthest from the master cylinder. Do it 2 or 3 times or until the brake fluid comes out in a steady stream. While you are doing this keep the master cylinder full and the cover on. This should give you back your pedal. Hope this helps.
