It appears that you have not bled the air out of the system. Get a mate to pump the brake pedal a few times then hold it down while you open the bleed screw starting at the nipple furtherest from the m/cyl. Hold down the pedal while you retighten the nipple. repeat the process until there is only oil coming out. Do this at all nipples until the pedal is solid. don' forget as you are doind this the oil in the m/ cyl resevoir will be going down so keep an eye on it and refill as necessary. Use only the correct brake fluid from an unopened container

SOURCE: mazda 626 (2000) ABS light comes on sometimes

This is most likely caused by an erratic wheel speed sensor when the car is turned on it does a abs system check. When the light goes on and off it is because probblem only shows up when wheel speed sensor signal is vaulty. Since you just did the front brakes and know the problem started, it is most likely that the sensor got damaged or misaadjusted. The other thing you need to check is, the sensor is magnetic and can catch alot of debris, like metal shavings from a freshly turned rotor or other metal particles. I would see if there clean and the reluctors are clean to, also check connection and wire make sure it was not damaged. The other thing that can happen but is least likely is that, materials can be pushed into the hydraulic control module. This happens by forcing the piston to the very bottom without opening the bleeder valve since, this is where dirt and corrosion usually accumulates.

SOURCE: Replaced rear calipers and need to know where to

Not 100% sure but peel back the handbrake lever cover.Beside the lever where the handbrake cable attaches there may be an adjuster there.Either directly on the cable itself or by locknuts threaded on the cable.Hope this helps

I have a 67 Bonneville with drum brakes in front. It pulls to the right when braking. I have readjusted both sides and replaced the flex hoses but still pulls. Any suggestions?


Justin, Not sure if you put in new brake shoes/drums etc. Brake Pedal should be firm not spongy when you press brake down, and not spongy. Push brake pedal down hard and hold, if pedal sinks to floor you have air in lines or bad brake wheel cylinder. When adjusting the brakes , Make sure Master brake cylinder is full!...Have the tire/wheel bolted on...adjust the brakes so brake shoes cannot be tightened up against drum any further. This will center the whole assembly. Wheel should not be able to spin whatsoever...Then back off the star adjuster to loosen one click at a time while trying to spin the wheel. Make so the wheel just barely turns without the brake shoe dragging (inside assembly) on the brake drum. Do the other side so it is exactly them same looseness as other. I like to have brake adjustment so wheel turns almost completely freely with a little drag from brake shoe. Then try driving. If still same pulling...Bleed the brakes to remove air out. (Should be You tube videos showing how) While bleeding brakes, remove master brake cylinder and refill with fluid after you bleed the brake line for each time you bleed then close the brake line bleed bolt/screw. After you do left and rt front...then trying driving again. IF it still pulls....You can disassemble the whole front brake system both sides and rebuild both of the brake cylinders with kit or buy new assembled brake cylinders and replace by simply unbolting old and bolt in new. Clean all brake parts and backing plate with brake cleaner spray from auto stores One or both brake cylinder pistons inside the cylinders maybe corroded/dirty and seizing up causing one side to be doing al the braking. It would be a good time to buy all new hardware kit for each front assembly as well as long as you have it apart. With brakes removed...have brake drums checked to see if still in spec...as drums could be worn out past spec...If worn uneven ...have them turned/machined just the minimum amount to bring back in spec. Good time to replace inner and outer wheel bearings as well if not replaced for long time. Be on the safe side...Many local car clubs have members who would be happy to help you. Check your local National Street Rod Association for help! There are repair manuals for your Pontiac you can buy as well. Some people might tell you to put on expensive disc brake conversion...Don't ...unless you are filthy rich. It's Simply not needed. Good Luck. Many online you tube videos showing you what to do.

What is the master cylinder


The brake master cylinder is the device that supplies hydraulic pressure to the brakes when you press the brake pedal. It is located on the drivers side of the vehicle under the hood back by the firewall. It is under the brake fluid reservoir. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Got my tires rotated and the shop informed me that my brakes had gone bad and needed replacing. Rather than spending 900 dollars I didn't have, i opted to do the work myself. Brakes work now, but...


that sounds just like a leaky none return velve in the master cylinder or very low on brake fluid it may even have got air in the system also if you removed the rear drums and never ajusted up the brake shoes this could give you this problem check the rear brums first the brake shoes should just be tuching the drums if there not pull off the drums and wind up the ajusters then refit the drum till the drake shoes are only just clearing the drum i know they have self ajusting shoes but half the time they just dont work very well so ajust it by hand,, the front brake are disk's and they are self ajusting,,,
after doing this work leave the car for a minue or so and stamp on the brake to pump them out if you then need to pump the brakes up again that shoes its just ajusted the rear drums,,,the brake pedel should only ever need to be prest once never pumped up,, if this dont help you out and sort out the problem then and only then replace the master cylinder as there normaly very strong and dont brake down often and they often leak brake fluid first,,,my bet is its the rear shoes needing ajusting up

Have you checked the clutch master cylinder for fluid? First place I would look. If you don't know what it looks like, it will be next to the fire wall drivers side- looks like a brake master cylinder, but smaller. Just use plain brake fluid in it.

1978 VW super bettle brake problem


Sounds like u r ready to drop the beetle off a cliff. U seem to be doing everything that should give u a firm pedal. 1st- I've never done brakes on a 78 beetle, but have done many brake jobs on others, so in general here are some possibilities: A couple of things, did u bench bleed the master cylinder? (put in a vise, fill w/ brake fluid, using screwdriver, pump piston to remove air). Although u don't have to do this, it saves time trying to get the air out of the system. Did u bleed the brakes starting w/ the farthest from the master cylinder, 'til all air out, then to next farthest away, etc til u do closest brake cylinder last? Made sure the master cyl. never ran down while bleeding and sucked in air? Does your 78 have power brakes? If yes, beetle was running while u bled brakes? Bleeding procedure: Have helper pump pedal approx. half way to floor, 3 pumps, on 3rd pump, hold it half way down, while u open bleeder, when flow decreases from bleeder, close bleeder, then helper can let foot off of pedal and pump 3x again, repeat til fluid shows no air. You probably know all this, just hoping u are doing something minor wrong, and this could help. Individual wheel cylinders aren't leaking? Let me know if this helps at all, if not, I'll try to come up w/ something else. Stay away from the cliff.
