Either the power booster has failed or the master is bad...If the noise sounds like air escaping, it's the booster.

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.

2004 f150 soft brakes


New to FixYa-not sure how this works.Soft brake are typically associated to a fluid/ master cylynder issue. Without viewing & knowing particulars via driving habits, mileage, etc, it is hard to duduce specific issues. Your front brakes have greater stopping pressures than the rear brakes which means they wear down quicker than the rear brakes. If you have a soft/mushy pedal, you may have worn brake pads which also leads to the brake fluid resevoir being low (shoe diminishment to increased fluid use-ratio)-you can fill the resevoir and pump up/ solidify the pedal but when you replace the pads, the fluid will overflow the resevoir.There are also indicators on brake pads that cause a high pitch squealing when the pads are low-again, without a visual or specific info like "do you hear any squealing while braking, how many miles on vehicle-the current set of brakes, do you tow anything, etc...", it is hard to diagnose; kind of like a doctor diagnosing a belly ache over the phone - there are so many factors/variables from the vagueness, it makes the situation a "guessing game"..If you can include more definitive info, it may narrow down the issue without a visual inspection. There are a lot of other components that could be the issues but the pads/low fluid will be the most common.Hope this does not cause more harm than good. G2

You're lacking some info about this issue. Who replaced the brake pads? It sounds like they may have been incorrectly installed. Another thing... You say "brake pads" but say nothing about the brake shoes. This leads me to believe that the front pads were changed and the rear brake shoes were not. If you do not know how to change them yourself, go to a reputable place to get them checked. Be specific about your problem and have them check the front rotors and brake pads and the rear brake shoes and the drums. It is quite possible that the rear drums need to be replaced or turned. Drums and rotors are fairly inexpensive so I would consider replacing them BOTH. With a little more info, I'm sure someone here could help more Good luck!

1988 subaru gl with brakes that are froze up. Yesterday there weren't any brakes , pumped them and the y came back. drove it a mile and the brakes slowly got tighter and then completely stopped the...


if it locked up all 4 wheels then it could be a few things to look at.Start with what color the fluid looks like,if its a tan to dark brown then its time to replace it,either it got contaminated or water in it.Next look at how much brake pad and shoe is left.A good rule of thumb is to put 2 quarters together and measure them to the pads,shoes,and if the pad is thicker than the quarters than there good for now.If pads and shoe's are good then its time to move on to the master cylinder,proportioning valve,lines(metal and rubber).If the master cyl is not returning enough fluid(pressure) then it will lock the brakes.if the proportioning valve is bad it will do the same thing(some master cylinders have the proportioning valve built in to them)you will have to check to see if u have 2 or 4 lines coming off the master cyl.if its 2 then they split off to the other wheels brakes so check that.then check the lines for leaking fluid(and could let in air).Sometimes the ruber lines break apart inside so u wont see it,and lodge in any of the part mentioned above and lock the brakes also.

My 1997 chevy 1500 z71 brakes suddenly going all the way to the floor. Checked brake fluid and it was low. Could be wheel cylinder? Master cylinder? or ?


well, check the brake lines for leakage after adding brake fluid to the full mark. If the brake pedal goes all the way to the floor, it's likely there is a leak somewhere after the master cylinder. If the pedal gets hard after adding fluid, and pumping it several times with the car off, then the master cylinder is still ok.

If air has gotten into the master cylinder, it may have to be bled out on a bench, or using a scanner if that's the way your vehicle is.

Bleeding the Brake System (ABS) Auto Bleed Procedure NOTE: Perform a manual bleeding procedure. If the brake pedal height and firmness results are not achieved, perform the auto bleed procedure below.
NOTE: Perform this procedure when replacing the brake pressure modulator valve or electro-hydraulic control unit.
  1. Perform the manual brake bleeding procedure. Refer to Bleeding the Brake System (non-ABS).
  2. Check the master cylinder fluid level often to prevent running the system dry.
  3. Press the brake pedal firmly and run the Scan Tool Automated Bleed Procedure (for Gas engines) once, or the Function Test (for Diesel engines) four times. Make sure to release the brake pedal between each test.
  4. Perform the manual bleed procedure again. This should remove the remaining air from the brake system.
  5. Bleed the system as many times as needed to obtain the appropriate feel of the brake pedal.

After replacing front pads and rear shoes on my 2006 Nissan Sentra I still hear what sounds like worn shoes, or pads dragging when I come to a stop. Neither the pads or shoes were worn to that point when...


to my knowledge , some brake pads have metal compounds , and some are aspestos , i once used metal type on my falcon years ago and found when they got hot it was like an MTT bus braking . these type were used on taxi's for longer endurance but made noise when hot , despite being fitted correctly .

sometimes if you have touched face of pads with your hands this will also cause this noise , if so remove and lightly rub with sand paper to remove any foriegn matter and replace carefully , also brake fluid from bleeding afterwards could cause this also , did you notice if there were any little plates behind brake pads , these little flat dust plates or anti vibration plates that are behind pads some times work better with a little silicon between them and the pads , this helps a little.

also on some models i have found the rear caliper has to be screwed in and pressed also , some hand brake systems require this to un adjust the hand brake system when replacing pads .
inside the piston of the rear caliper will have a cross shape if so ! be care full if so , as one is right hand thread and one is left , if they a screwed the wrong way the piston is very hard to re-align the thread again without the chance of cross threading ..

hope this helps !

How can i tell if master cylinder on my 91 buick park ave is done the break pedal goa all the way down as soon as i turn car on. o not see any fluid leaks. car stops if you pump breaks but slowly?


Most likely you need brake job on front and rear. to test if the pads are worn on the rear set the emergency brake then push down on the brake. does it come up? if it does This means the rear pads are bad and most likely the front. You will want to check the master cylinder for fluid if it is low you will have to replace with DOT3 Fluid once it is full you may have to bleed the system to see if the brakes come up. If the fluid is ok and The pads are not wore out then you will have to check the master cylinder to do this you need to jack up the car one wheel at a time and test by pressing brake pedal down slowly till the wheel will not turn. If the wheels stop on all four wheels when you have done this test then you will need to replace the pads and shoes. If the master cylinder is defective either the front wheels won't stop or the rear won't stop turning when you press the pedal down. The Master cylinder is $39.00 with exchange, but you want to make sure the pads are good the rear shoes are good and the brakes are adjusted. Here is the web page for the parts you need. If you need help doing a brake job let me know and I will give you whatever information you would need to do the job with. You can test the master cylinder if you have rubber gloves too, just pop the lid off the master cylinder and have someone slowly push the pedal down with your finger on the front port see it you get fluid blowing out the hole when the pedal is pushed down. If you do the cup is bypassing and it needs to be replaced. Hope this helps.

1999 Dodge Ram 1500 conversion van rear brake hammering


Are the brake shoes on right, there are two size shoes, One shoe has a longer brake lining then the other. The short brake lining is towards the front of the van and the longer brake lining is towards the rear. The rear brakes also may need to be adjusted, you can do that by going in revers in a empty parking lot and push the brakes as hard as you can to stop the van. Don't give your self a whip lash, just push down gradually and as far to the floor you can about 7 to 10 times. The self adjusters should adjust the brake on both sides, try this first before you take the brakes apart again. It may just need a adjustment and after that check the brake fluid in the master cylinder. Good luck and hope this helps. Keep me posted, be glad to help

'04 Corolla Grinding noise when breaking


Even though there may be some brake pad remaining, sometimes you need to machine or replace the rotors in order to get rid of a noise. Rotors can develop a bad wear pattern that acts against a glazed pad to produce a loud noise even if they are not worn out. Replace the front brakes, pads and rotors.
