Sounds like still air in the system...re-bleed...be sure to start at rear wheel farthest away, then next rear, then away front, then close to master cylinder...also did you bench bleed the master cylinder?

check to see if one of the caliper bolts came loose or one of the bracket bolts--could also be a twisted brake line

SOURCE: Cross diagonal braking system on a 01' Accent,

if your vehicle has anti lock braking you may need to get the air out of the pistons. make the anti lock brakes work (this can be done on gravel relatively easily) then bleed the system one more time.

SOURCE: Have replaced all 4 brakes

a leaking brake master cylinder will allow air back into the lines after a bleed.

The front drivers side break keeps locking. I have replaced the caliper and now when I pump it no fluid is coming out from the line.


Did air get into the master cylinder? If you can, try bleeding the master cylinder. The fact that you aren't getting any fluid out of the line suggests that the master cylinder isn't pumping fluid.

Master cylinders are (usually) on a split circuit system - that is, the front left brake is on the same line as the rear right. The front right brake is on the same circuit as the rear left.

A point to be aware of is when bleeding brakes/doing brake work and if the master cylinder runs dry, is that a seal inside the master cylinder can fail/twist over and not pressurise that particular line, even though it may pressurise the opposite brake line.

I'm in the UK. I have a 1998 Jeep Grand Cherokee 4 litre, which I am slowly rebuilding. Three weeks ago I fitted new front brake rotors, new front callipers and pads. I've been rebuilding cars for over 40 years now and have done countless brake overhauls.

.. and could I get a hard pedal after the job was completed? I must have bled the brakes three times a day for a week and couldn't get a brake pedal. I phoned a full time mechanic I know - he came and tried to bleed the brakes three times and couldn't get a hard pedal.

That's when you think 'The master cylinder was working before I started the job so it must be still working now'.

I fitted a brand new master cylinder and because some parts for older jeeps are hard to come by in the UK, I fitted a second hand proportioning valve. When I bled the brakes again the pedal became rock solid. Fixed.

You're probably fed up with your braking problem now ... and apparently this 'no fluid/brake pedal' is more common than you may think.

Try bleeding the master cylinder if you can. If you suspect that it isn't fully working - try an overhaul kit which is cheaper than a new master cylinder.

As for changing the proportioning valve .. that's your decision. My brakes now work though the truth is I don't actually know which was at fault as I changed both the master cylinder and proportioning valve at the same time. Maybe both were at fault, for whatever reason. I genuinely don't know.

The positive aspect is that you are doing your own work and know what you're doing. You're saving on labour charges.

I have a 2002 bmw 325i E46. I do not have a full brake pedal unless I pump the brakes a couple times. If I slam on brakes hard, the brake light comes on the dash. The brakes have been professionall


pumping the brakes is an indication of out of adjustment brakes. However if you have disc brakes all around then that will not be the case. IF you have drum brakes on the rear then the brakes have not been properly adjusted . Pressure bleeding does not necessarily mean that there is no air in the system. I suggest that there is still air in the system in one of the circuits from the master cylinder or the master cylinder has not been primed before fitting
May be you should have the problem investigated by an accredited brake shop before something drastic happens.

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

Brakes on a Lincoln mark viii coupe 1995 fitted new M/cylinder L/front and R/rear wont bleed is somthing wrong in the abs and how much for a new unit


All four brakes must be bled to eliminate the trapped air...probably not anything else...try lubricating the bleeder fitting with PB Blaster before trying to open...be cautious as this valve can break off, and that means rebuild the caliper drill out broken fitting...or replace caliper...either way all 4 brakes must be bled...start with the rear farthest away from the master cylinder then other rear...then right front, then last is left front...Hope this helps.

If the car has Drum style rear brakes, make sure the adjustment is good. It takes a lot of fluid to activate them.

I put a new master cylinder on my car need help on how to bleed them please


The master cylinder should have been bled before installing it. The fittings and a small section of rubber hose should have came with it. If you have these fittings, you can still bleed it without removing the castercylinder. Install the fittings where brake lines come out and run the rubber hose into the "full" master cylinder and have someone pump the brakes slowly until all the air bubbles disappear. Reattach brake lines and the master cylinder should be all set. You will probably have to bleed brakes at each wheel

Spongy brakes


So long as the brake booster is working, test it by turning on the engine, press the brake pedal all the way down, then shut off engine keeping your foot on the brake pedal, if the pedal comes up slightly pushing against your foot then the booster IS working.

Did you BLEED the brakes??????

I have bled brakes replaced front pads and even replaced rear passager wheel cylinder and re bled brakes still not working when car is running


Did you run out of brake fluid , if you did the brake master cylinder seal may have reversed and when you are trying to bleed the brakes the fluid is bypassing the seal , you think you have a good pedal when the engine is not running , but when you start the engine the pedal goes to the floor , you will need to fit a new or second hand master cylinder to cure the problem , I had this with my sons car and the problem was cured with a second hand master cylinder , I hope this helps

Just replaced master cylinder on 1990 aerostar and bled the brakes, still the pedal goes to floor and i have no brakes


Did you bench bleed the master cyl. before installing it? then when you installed the new master, did you bleed all 4 points? If yes, then check all for points for leaking caliper/s and leaking wheel cylinder/s. If the van has ABS, check the valve body for a bleeder screw and see if air bleeds out of it. If you've checked everything twice and did everything right then your new master cyl. may be defective.
