Re: Brake light displays
Look at the master cylinder fluid level. If it is low, the red brake lamp will come on. Note that as the front brake pads wear, the brake fluid level will drop proportionally. If the fluid level is indeed low, you may need front brake pads, Unless you have a lot of miles on it, I doubt that you will need rear brake shoes. Also, if the fluid is low, don't add any. When you DO have to replace the pads, the additional fluid will be forced out of the cylinder and get all over your engine compartment under the master cylinder area . Brake fluid will eat the paint. Check the brake pads, replace them if the pad material is worn.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Sometimes if your rear sensors are in the brake backing plates, you will get debris from the Emergency brake pads and this will affect the sensor count. As the wheel revolution is perceived to be different from one rear wheel to the other, the Traction Control system automatically activates and applies the brakes to make the wheel revolution match on both back wheels.
The Emergency brake linings can fall off of the shoes and create this problem. The brake pads in the front can also separate from the front discs and make the ABS warning illuminate.
Best have a Brake shop remove the rear brakes as they can be a pain to get off when the Emergency brake linings grind up.
You say you filled it with fluid after the repairs. You must also "bleed" the brake lines to purge any air that is trapped in them. Brake fluid provides the hydraulic compression that causes the brake pads to clamp to the brake rotor/drum. Air in the lines will prevent this as when the brake pedal is pressed, the fluid will simply pressurize the air in the lines and not activate the caliper/wheel cylinder. The reason you have front brakes is that modern vehicles have dual-reservoir master cylinders to prevent total brake loss in the event of a leak. This is why you still have front brakes as there is no air in those lines. You will need to bleed the rear brake lines at BOTH rear wheels to purge air rom the system. The procedure is fairly simple, though some cars with ABS have to have things done differently. I would recommend you check an online forum for you vehicle (simply Google "bleed rear brakes 20xx VW Golf) and see what comes up. It is easier to do with two people, but one can sometimes pull it off.
is brake pedal hard to push down without engine running ,if so proceed to step two and thats to start engine and then push on brake and if pedal softer to push then the servo is working ,now if excessive pedal travel with engine running then remove the rear drums ,make sure the outside lip is cleaned out and then adjust the brake shoes manually till they rub when you turn the drum ,this will cure it but remember that it has to bed in of course new pads brake disks ,new shoes and drums it has to bed in so give it a chance .
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads and the 4 anti-squeal shims
CAUTION Only replace brake pads on 1 side of the vehicle at a time. Failure to use this procedure could cause the caliper pistons on the opposite side of the vehicle to pop out requiring the reconditioning or replacement of the brake caliper.
Remove a small amount of brake fluid from the master cylinder.
Install a used brake pad into the caliper and compress the caliper pistons.
Apply disc brake grease to both sides of the inner anti-squeal shims.
Install or connect the following:
Anti-squeal shims to the new brake pads NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.
2 brake pads
Anti-rattle spring and the 2 caliper pins
Depress the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off as needed.
Normally when the brake pedal goes almos to the floor it is an indication of low brake fluid. Low brake fluid is an indication that front and/or rear brakes are wearing. As the brake pads wear down more brake fluid will be required in the wheel cylinders or calipers. Hint, the front brakes usually wear much faster than the rear due to the fact that the fronts due a much greater braking function that the rear. Check the front pads. Don't let them get down to the metal scraping metal stage before you change them out. This causes unnessary damage to the rotors. Look at your master cylinder on the firewall under the hood in front of the steering wheel. If the fluid level is belowhte "max" mark add fluid. Low fliud should also show as a red "brake" light on your dash, but not always.
Its probably how your bleeding your brakes, but first make sure the bleeding nipples are facing upward. You should bleed diagonaly, front pass wheel then rear driver wheel. Then front driver wheel and rear pass wheel. The abs light has its own computer your have to get it scanned to clear the codes and turn off the light
