When you fitted the booster and master did you check that rod had some clearance. The rod may be holding the piston partly in and this will stop more fluid entering.
When bleeding brakes you always start at the furtherest from the master cylinder and work your way back.

Hi Eddie:
Let's see what we can do to try to figure this out. First, tell me about the brakes. Disc front? Drum back? All drum?
If there are drums, the shoes have to be manually adjusted with the little threaded spreader bar. Discs self adjust.
When you're bleeding the brakes, keep lots of fluid in the master cylinder reservoir, and start with the front wheel nearest the master cylinder, then the other front, then the drivers side rear, then the other one. The idea is to try to avoid getting any air trapped in a line. Once you.ve done it right, the brake pedal should have a firm STOP when applied.
If the pedal continues to go to the floor, I'd be concerned about the master cylinder.
Hope this helps

    The front brakes are disc and the rear are drum. I just bought the whole kit for the front brakes,rotors,booster,master cylinder,etc.. the rear drums had been adjusted prior to me putting on the front brakes. Should I readjust them?

  • Ted Maxwell Apr 28, 2015

    Hi Eddie: Rule # 17 - never trust what someone else did if you still have a problem. Considering the work you've done, you should be able to remove the back wheels and take the drums off to have a look at the shoes. When you go to put the shoes back on, adjust the spreader bar so that the shoes are nice and snug while still being able to have the drum slide over. There is a slot in the backing plate that lets you adjust them once the wheels are back on. Takes a bit of figuring to determine which way to tweak them. They self adjust when you back up and pump the brakes, but considering you have no brakes that might not be a good thing to try. Hang in there. Ted Oh, It looks like Terry and I were taught different procedures for bleeding brakes. My Guru's theory was that there was less chance of having residual air in the system if you bled from the shortest to the longest. Hey, we could have a whole new topic. Cheerfuls,

Start from the furthest away from the master cylinder and work your way forward..And make sure who is helping you bleed them they hold the brake to the floor and dont let up until you've tighten the bleeder screw..And make sure your master cylinder is full every time you bleed one tire so that you dont run out getting more air in the systems..Hope this helps you and Have A Great Day

SOURCE: Brake pedal goes down to floor. Putting brake fluid doesn't solve problem. Vehicle must coast to a complete stop.

First look for obvious leaks under the vehicle, especially the inside area of each wheel... If you see fluid, you have either a blown cylinder seal or a bad line (check the rubber hoses to the front and back brakes too) Repair the offending part and bleed the air out of the system... (remember to clean pads or shoes if they have fluid on them)... If you see no hint of leakage anywhere, then suspect the master cylinder... if you remove the master cylinder, check and make sure that it didn't leak fluid into the brake booster diaphragm (Brake fluid will destroy the booster)... as in any repair when you open the system (lose fluid), you will need to bleed out the air to restore function... hope this helps...;-)

Yes, you can bleed them. But unless you opened the lines when you changed pads, you shouldn't have gotten air in the lines. Are you sure both brake reservoirs are full? If they are, then try bleeding. Start at a rear tire and move to front, with the driver's side being last one bled. Check carefully for any signs of brake lines leaking.

Brake pedal goes to the floor


This means there is a leak in the brake fluid circuit or that the master/brake cylinder has failed. Look into the brake lines and observe the leak on the wheels or the master cylinder. If so the buckets of the cylinders must be replaced as well as the fluids must be refilled after work and the system must be freed of air by bleeding.This will make the brakes work with full effort and a good pedal.

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.
