I HAVE A LEAK IN BRAKE LARGEST RESIVORE, WHAT IS PROBLEM?


the brake fluid will go down as the brake pads wear. it also can leak at any wheel cylinder check for brake fluid on tires, the front of the master cylinder can also leak in to the brake booster. a brake line can leak if hit by stone ect. If some one presses the brake pedal that kind of leak will show up.

Replaced some brake line, rear pads and one rear wheel cylinder. Now no pressure and nothing happening when trying to bleed.


Does the car have ABS ? And does it have an equalizer block for the 4 wheels ?
It sounds like the ABS has been affected, or there is an equalizer block that is stuck on the front wheels only.
Can you open the bleeder or the rear line on the master cyl and get fluid to come out by depressing the pedal ?

How to bleed the brakes on a1999 chevrolet venture van instaslled new brake pads on front tired to bleed brake pedal all the way up when van not running - goes to floor when van is running


Start with brake in the rear that is the farthest away from the master cylinder ( if your master cylinder is on drivers side start with passenger rear,pump up brake pedal until hard have someone else open bleeder valve until air or fluid squirts out,while holding brake pressure even if goes to the floor dont release pedal until bleeder valve is tightened or you will **** air back into the line,do this several times making sure you get a full stream of brake fluid and no air,continue to other rear wheel and then proceed to front wheel furthest from master cylinderand then final wheel. if you still don't have brakes change master cylinder and bleed all brakes again.

98 dodge caravan just changed master cylinder and the pedal still goes t6o the floor was doing this before also


Check the fluid level in mastercylinder first. Inspect brake lines for any leak. Also it could be a leaking caliper piston on the front brakes or a wheel cylinder on the rear. Will have to remove the tires on front to inspect and if you do not have rotors on rear you will have to remove the brake drums to inspect for a leaking wheel cylinder. Hope this will help you.

Break pedal goes to floor with light pedal pressure used during stop and go situations (i.e. in town driving). Hit pedal hard and brakes grab at normal range.


renew the master cylinder immediatly ,the seal between the front and rear chambers has failed. This is a dangerous vehicle and shouldnt be used in this condition it WILL FAIL SOON

Pedal almost goes to floor, see steam or smoke from front wheels


Definitely sounds like you have a brake fluid leak. It shouldn't be driven anymore until the problem is repaired. The red brake light comes on when the fluid is low. If your in a rusty climate one of the brake lines has probably rusted out. When it dries up try following the lines from the master to each wheel. However since you said you saw smoke when braking i'd bet the leak is near a wheel and fluid hit the rotor or caliper which caused the smoke. In either case, sounds like something has to be replaced / repaired. Good luck.

2002 chevrolet avalanche how do you know when brake booster out no pedal onley 1 inch from floor when pressed replaced the abs control module but had this problem before the module went out


If you have a bad booster you would have a really hard pedal and it would take two feet to stop. Sounds more like a fluid leak or a bad master cylinder. Are you adding fluid or do you have a red brake light on?
