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.

Soft pedal on 03 grand caravan


Have you driven it since the brakes where replaced?

Did you bleed all four wheels?

have you "broken in" the new pads?

Are the rears drum or disk? If drum are they adjusted correctly?

are you using remanufactured master cylinders? If so keep replacing them. eventually you will get one that works. New is pricey but a better way to go.

I have no brakes


It can be issue with master cylinder or the problem is there is still some air there in the system that has to be bleed. Or else the parts replaced are not aligned properly/.I suggest everything back.

I changed the front brake rotors and pads also the rear cyliners and shoes and bled the rear brakes but not the front because i didnt disconect the front brake lines. So why is my brake pedal so soft? and...


keep bleeding and bleed the front as well the littlest amount of air will keep pedal spongy if the abs came on after doning brakes check the abs lines and connections up front the abs lines sometimes get banged up will doing brake job the abs sensor is the wire that runs from behind the rotor to the fire wall sometimes they get hit knocked into or damaged if wiring looks good have vehicle scanned for code .the code will make it easier to pinpoint what side-- if circuit problem--or if sensor went bad most auto stores offer scanning for free

Spongy brake pedal even after ABS bleed and base brake bleed.


Did you adjust the rear shoes out? If the rear drum brakes are out of adjustment they will give you a lot of pedal travel. If the pads are worn have no fear of that U-CLIP brake spring, just change one shoe at a time. Take the spring off one side, change the shoe, put the spring back on the post and do the same to the other shoe, no problem.

1999 Chevy tahoe 2dr Brake shudder intermitant hard pedal.


You probably need to surface the rotors and the drums. I have gotten brand new rotors that were so warped that they were below min. thickness (not kidding) after surfacing them. Needless to say, they went back to the parts store. So now I surface every new rotor that I install. Happens to rotors way more than drums, but have hade a couple of drums that were warped when new so I check them before installing them. Good luck. Hope this helps.

Spongy brake pedal


I have a 2001 Chevy 1500 4 X 4 that recently had all new pads, rotors, and calipers installed. Since then my brake pedal goes almost to the floor before I get any brakes. I took it back to the shop and they bled the brakes with no better results. I bled them also with no results. I took the truck back and they installed a master cylinder with no results. It's now at the Chevy dealer and they say it's normal - BS! I had good brakes before I had all of the brake parts replaced, no one can figure it out. If you have a load in the truck or if you tow anything you better be looking at the ditch to avoid an accident. The original brakes would put you nose into the windshield and now I could stop it better the Fred Flinstone way. Anyone have an answer????????

ABS braking


have you check? the master cylinder. sometine when you get the rotors cut they dont come out right because they may be warped or to thin. if you did the job yourself you might have put the calipers in on the wrong side. this happens alot . if your rotors front and rear are fine then switch the calipers to the other side.
