Probably a broken brake line. Most brake and muffler shops can handle this type of repair. New line must be installed and system bled od air.

Brake pedal often goes almost to floor-not spongy at all-doesn't seep if pressure constantly applied.


Hi,
Probably air in the brake system. Bleed your brakes thoroughly. Start with right rear, then left rear, then right front then left front. Maintain proper fluid level in master cylinder while bleeding. Brake pedal hieght comes from the rear brakes, as those are the longest brake lines in the system. Mike

What are the proper steps to bleeding your brakes on a 1990 vw golf deisel


For left hand drive vehicles: (If the car does not have ABS system you do not need any diagnostic equipment!)

IMPORTANT NOTE: You need using diagnostic equipment connected to the data link connector of the car in order to bleed the ABS block. Follow instructions by scantool equipment for bleeding the ABS block.


1. This bleeding procedure requires two people. Remove the brake system reservoir cap, and fill up with new brake fluid until "MAX" level is reached.
2. Lift the car, or use a channel for access under vehicle.
3. Put the gearbox in "N" - Neutral position, or in "P" - Parking position for automatic transmission.
4. Start the engine and push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor.
5. Begin with the rear right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
6. Repeat steps no.#4 and no.#5 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

7. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
8. Continue with the rear left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
9. Repeat steps no.#7 and no.#8 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

10. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
11. Continue with the front right wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
12. Repeat steps no.#10 and no.#11 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.

IMPORTANT NOTE: All the time check the brake fluid level in the brake system reservoir, and fill up if necessary!

13. Push the brake pedal firmly for 4 - 5 times to the floor, and maintain the brake pedal pushed to the floor, engine idling.
14. Continue with the front left wheel. Another person remove the dust cap and loose the brake caliper bleeding screw until the brake pedal goes to the floor. At this moment maintain the brake pedal pushed to the floor, engine idling, and tight the brake caliper bleeding screw. Use a plastic hose: one end connected to the brake caliper bleeding screw, and another end inside a recovery bottle for used brake fluid.
15. Repeat steps no.#13 and no.#14 until no air flows through the brake caliper bleeding screw. Tight the brake caliper bleeding screw, and put the dust cap in their place.
16. Now the brakes are bleeded. Check the brake fluid level in the reservoir. Fill up with new brake fluid until "MAX" level is reached. Put back the brake reservoir cap.
17. Test the car brake system. The brake pedal movement no more than 1/3 of total stroke until the floor, when brake pedal is applied. Maximum admissible is 1/2 of total stroke.

My brake pedal is on the floor and the brake fluid continuously goes low. It seems like the vacuum pressure never builds to keep the pedal off of the floor. Any ideas?


You will need to carefully inspect the entire brake system for leaks. Inspect the front calipers, rear wheel cylinders, all the hoses, the back of the master cylinder, and steel lines. If something looks wet or drips brake fluid it is leaking. If you haven't seen any brake fluid dripping from under the car my first thought is that the rear wheel cylinders are leaking.

If the pedal went to the floor and you didn't have to add fluid than you would more than likely have a bad master cylinder but since you are adding fluid there is a leak somewhere.

1993 Mercury Grand Marquis, Brake fluid leaking under left rear door. Brake pedal goes to floor. How can i fix this?


Hi, the reason the pedal goes to the floor is because the brake line going back to the rear axle blew, first you will need to find where the hole is and cut out the bad section, usually you can find a clean spot further down that you can cut out the bad spot. you will need to go to the parts store and get a new piece of brake line and a tubing cutter and a double flare kit. usually you can rent one of these to save money.

It sounds like you have a bad mastercylinder cause when you panic brake it doesn't have time to bleed through the valve in the cylinder but under normal braking your foot is on pedal longer in turn giving the fluid time to bypass the valve in the mastercylinder in turn the pedal going to the floor.

Brake pedal goes all the to the floor. can not


Check the reservoir to be sure the fluid is full. If not, top it off and try it again. If there's still trouble building pressure, pump the brakes a bunch of times, and then check around each wheel for fluid on the ground. If you see none, it's possible that you have a break in the line somewhere through the chassis and that the fluid is leaking out inside. If you see no evidence of leakage, and the reservoir is still full, you need a new brake master cylinder - what will have happened is that the diaphragm around the plunger inside the master cylinder (which moves through the cylinder when you push the pedal, and forces fluid out to the wheels) has a hole or tear in it, so instead of pushing the fluid out to the brakes, the plunger simply moves through the fluid. It never builds pressure, and your brakes don't work.

When apply brake car not stoping (cadillac 2001 STS car )


you need to bleed all four corners and when doing so use a hose from the bleeder valve into a clear jar half full of brake fluid. Keep The Hose Under The Level Or Air Will Get Back Into The System.
When Bleeding Close The Valve And Have Someone Push The Brake Pedal 1,2,3 Hold Then While The Person Is Still Holding The Brake Slightly Open The Valve Then Keep Doing It Until You Don't Even Get A Bubble. Do This On All 4 Wheels And You'll Be Good To Go.
The More Air That Comes Out The Harder The Pedal Will Get. Make Sure To Keep Filling The Reservoir Cause If It Empty's You'll Have To Start All Over.
