SOURCE: keep getting air in break lines

1. bleed your vehicle while the engine is running. 2. Check ALL your brake lines, connections and wheel brakes cylinders or calipers of any leaks or moisture. 3. If nothing happens, your brake masters or your caliper's pistons may be weak and needs replacement.
post me of any development

SOURCE: brakes

Step1
If you had a brake job you might have air in the system that needs bleed out.
Crack open the bleeder on the caliper and watch the brake fuild come out steadly and close it and don't pump the pedal. Do this to each side this is called bench bleeding and watch the brake fulid level while you are doing this add fuild as you bleed each side.


Step2
Also sounds like a leaking line check under the car for a leaking brake line. Next would be a master cylinder problem. But more than likely a brake line might be rusted up and leaking, sooner or later you will not be able to stop. If its a leaking line it will leak all the fuild out of the master cylinder. You can replace the line and use the bleeding procedure in step one.

Probably blew the rubber diaphram in the clutch master cylinder. Rebuild kits are fairly cheap and easy.

My brake pedal slowly losing pressure goes to the floor and then I have to pump it up again


If you break fluid level is correct and your break pedal goes down to the floor means that your master cylinder is going bad and you might loose your breaks completely if not checked or replaced. Your breaking system is down to the last O ring inside the master cylinder, once that rubber O rings goes you will not have any breaks at all. Master cylinders have a number of rubber O rings that work like a plunger or piston that produce pressure within the breaking system. When the first one wears down due to age, your pedal begins to loose break pressure and you have to pump your breaks several times to gain breaking. You are now down to the last rubber O ring and a warning that your master cylinder needs to be checked. You can still use your breaks but only for a few days before the other rubber O ring gives out too. Once both O rings give out you completely loose your breaks.

Soft brake pedal on 94 gmc sierra


in late model GM and Ford cars with quick take-up master cylinders, the quick take-up valve takes about 15 seconds to reseat after the brake pedal has been depressed, so you should wait at least 20 seconds before you press the pedal while bleeding. If the pedal is pumped too quickly while manually bleeding the system, you may never get the pedal to firm up. On a side note, did you check the level in the master cylinder after every 2 or 3 bleedin procedures? you could have been pumping air right back in the lines if the reservoir runs dry during the bleeding process.

When i press the breaks the breaks pedal goes all the way to the floor


you either have a busted break line or your master cylinder needs to be replaced. check around all wheels for fluid leakage , If no fluid seen check to see if the cylinder is full , If mot fill it and pump the breaks and look again for fluid leakage.

How to bleed front brakes?


hello, your going to need a buddy in the truck pumping the brakes while you bleed them. With that first you need to verify that the master cylinder is full, if it is you can get started, there are two ways you can do this, the first is called a non-pressure bleed, this is when you break the bleeder loose and have your assistant push down on the brake pedal and when it is all the way to the floor you tighten the bleeder up before they release the break pedal. The second method is the pressure bleed. this one is a little bit more messy, you will have your assistant pump the brake pedal several times and hold firmly while you break the bleeder loose, the pressure will force the fluid and air out quickly. you will have to bleed both wheels untill there are no more bubbles in the fluid coming out. be sure to keep checking the master cylinder to verify that the brake fluid is full.

Brake pedal still goes to floor 2000 GMC Jimmy


It's very possible to be the master cylinder, the o-rings on the piston could be worn, letting the fluid seep back through instead of getting full pressure through the lines. Could also be the brake booster.
Try changing the master cylinder first, which is cheaper and easier, and see if there is a difference, you'll need to bleed the brakes again.
To check the booster,
With the engine off, pump the brakes until the pedal is hard, then hold pressure on the brake pedal and listen for air escaping, or the pedal goes slowly to the floor, Do that after the master cylinder has been changed, at least that will be eliminated.

How do you bleed brakes on a 1999 GMC Sierra with ABS 2wheel drive 1500 series


The rule of thumb is to start as far away from the master cylinder as poss. so it means you start at the right rear, left rear, right front, then at last left front. There is a little a little weep bolt on each calliper it needs to be un lossened when break is fully applyed then tighten weep bolt back up pump the breaks while weep bolt is still tight then hold brake pedal down to floor lossen weep bolt till a full steam of fluid comes out tighten bolt back up, now move on to the next break calliper and repeat this same proccess till you finished. Hope this works better than r/r l/r r/f l/f lol!!!!
