Bleed the brakes. RR,LR,RF,LF
You have to have a hose on the bleeder valve going to a bottle, to catch the fluid.
Put someone in the car,start engine,when the person says DOWN,you crack open bleeder valve and close before they get near the bottom.
Tell them not to, go to the floor,or you could cause damage.
Should put car on 4 jack stands to speed things along.
Did you machine or replace the rotors. If not ,start over?
I hope you sanded off ALL rust and lubed the caliper support bracket and slippers. Use Permatex Anti-Seize

    I agree with redbear. I own a 2004 LS, and you don't need to open ABS with a scanner,if you don't run out of fluid in master

If you have bled the air out at all four wheels, finishing with the R/R last. And you still don't have a good brake pedal, with the car running, then you may not be able to finish this job. Because of the modern ABS system, it requires internal solenoids to held open to bleed the brakes. A good scan-tool is needed to perform this task. Make sure the master is kept full. It can never be allowed to run out, not even once or there will be air all over.

Brake pedal goes to floor


for the pedal to go to the floor there is still air in the brake system. Start again starting from the longest line bleeding each in turn to the shortest line . make sure you have adjusted up the rear brakes before bleeding as every time you press on the pedal the shoes expand right out and when you take your foot off the pedal the shoes go all the way back in. adjust them manually and do not rely on the self adjuster as it only adjusts on wheel movement

Your brakes are vacuum aided so when engine is off the pedal will be hard. When the engine runs the vacuum is active and the pedal becomes light. Your brakes are working but need adjustment so that the pedal does not go to the floor.
Locate the adjusting screws behind the rear wheel drums.
With one wheel jacked adjust the shoes till wheel wont turn.
Then loosen until wheel is just free of any friction from shoes.
Repeat for other side.

How do i bleed new brake caliper


Press brake, let off. Open bleed screw until the fluid runs out with no bubbles. Tighten bleed screw. Press brake and hold. Open bleed screw until pedal goes to floor then close bleed screw with pedal pressed to floor.. Fluid should come out with no air bubbles when open. If they are present repeat the last part.

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.

You need a helper, to slowly press the brake pedal down, as you open bleeder valve,then close before your helper gets near the floor.
Repeat until all air is out of each wheel position.
RR,LR,RF then LF. Always start from the farthest wheel and have motor running
Never pump brakes. That does nothing at all.

Bleeding front brakes and brake pedal still goes to floor board


Must bleed all four brakes to determine if there is air in the lines.

If after bleeding several times, the brake pedal still goes to the floor board, the master cylinder may be determined to be bad.

New front calpers can,t get bleed spongy pedal


sometimes it may take a while to bleed the brakes, to bleed the brakes you need two people. to bleed brakes properly: make sure car is off and brake fluid is full, have someone pump up the brake pedal until it feels hard and hold it down once it is hard(make sure when you loosen the bleed screw the person pushes the pedal to the floor), have another person loosen the bleed screw until the brake pedal is on the floor of the car. repeat as needed and check the brake fluid often when doing this
