Depending if its front or rear if its in the rear most likely the brake wheel cylinder , and your brakes is part of the traction control why its off, you should make sure brake fluid is full and get it fix

Going up a hill, traction and break lights comes on (service traction-break fluid) message on my screen, got to top of hill and slowed down, lights came off. 2008 pontiac g6


Make sure your brake fluid is at the correct level. Any issue with the brake system will cause the traction system to not work as traction control works by modulating the brake on the wheel (s) that are slipping. If fluid level is fine then the sensor for the fluid level may be bad.

Brake fluid switch problem and traction disable lights come on. have check fluid and replaced brake fluid sensor and still have problem


It may be a wheel speed sensor at fault.
To be quite honest, you'd have to get it checked at the dealership or a workshop which has the correct scan tools.

Rear passenger brake dosen't work


Are there two brake fluid reservoirs? And are both full? This would be a split-diagonal brake system-front driver and rear passenger are one brake system. Front passenger and rear driver are the other system. You have the one system working-the front passenger and rear driver side works. You will have to keep bleeding the rear passenger side and the front driver side-always start farthest from the master cylinder, but if that wheel just won't bleed air out, make sure the driver front is working and bleeds good. If all else fails, there are pressure bleeder kits available, I don't know the cost, but they work great. They are also a one man bleeding job, as I understand.

Yes you can fix it. Jack wheel off ground after loosing lug nuts. Take off wheel. Pull drum if it wont come off hit it around the center with a hammer. If it has never been off there might be little washers on the studs break them off. If drum still won't come off there are holes in the plate behind the drum the shoes can't get past the ridge on the drum so you take two screwdrivers through the hole and lift up on the lever and use the other one to unscrew back off the shoes by moving the wheel up or down Remove drum take a bunch of pictures of the shoes so you can see how to put them on. Remove shoes. It would help to buy some cheap brake wrenches.Spray the brake line with some type of penetrant and remove brake line. Unbolt wheel cylinder and install new one. Replace brake shoes and springs Have drums turned or replaced if bad Install drums and bleed brakes.Start at the passenger rear fill it with brake fluid put cover on and have someone pump the brakes until the pedal is as hard as it will get Hold the pedal down and loosen bleeder screw on back of wheel cylinder brak fluid will squirt out and when it stops him holding his foot on the floor tighten the screw and pump the brakes up hard again bleed it about 8 more times go to the drivers rear and do the same there then the front passenger side and then the front drivers side make sure the brake fluid stays full if it empties out of the master cylinder to the bottom you will have to start over12_9_2011_6_45_35_pm.jpg

My traction control light and anti lock light popped on today and now the brake light popped on. i read the manual and it says to switch the traction control button back to on but i can't find it


I think your traction control button is on the center console behind the Shifter.
But, I don't think that is the problem. That switch will cause the traction control and light to turn on and off. It should not affect the brake light and anti-lock light.

I would first check your brake fluid level. Top it off with the correct fluid. The fluid is a DOT number; like DOT3 or DOT5. Use the correct DOT fluid.
If the fluid is very low, you may need your brake fluid system bled to remove any air. And you may want to check the brake pads. Low fluid may mean you need new pads.

If that doesn't work, go to an auto parts store that will scan your car for ODB2 error codes. AutoZone will do it for free. I suspect you may have a bad wheel bearing. That will cause the ABS and Trac lights to go on. I've replaced GM bearing/sensors on several of my cars. The last one was my 2005 Bonneville. The bearing and sensor are combined in one unit.

Traction control light on ,brake light on ,abs light on


If the brake light is on, check the fluid level immediately and add fluid if necessary.
After that, have the car's OBD-II computer scanned with a 'Brake Scan' tool for OBD-II. This will help to narrow down which wheel speed sensor is giving you trouble. It might be a broken wire, or a bad wheel speed sensor.

The wheel speed sensor sends information to the ABS side and the Traction Control side of the computer module for ABS and Traction Control.

The car will revert to standard braking and regular non braking transmission power distribution to the drive wheels when the ABS and Traction Control lights are both on.

Good luck on this repair.

Brakes only working on driver side, rear and front, no brakes on passenger side rear and front. fluid good, lines good.


There only a few things that would cause this that you need to check, first start at the front wheel that doesnt work, have someone applie the brake open the bleeder screw if fluid sprays then caliper is bad or caliper slides are frozen, if no fluid comes out then you have a bad brake hose at that wheel, do the same to rear if fluid comes out of bleeder in rear then wheel cylinders are no good if no fluid comes out then brake hose to rear wheels is no good, make sure to have pedal pressed and repush pedal when checking the rear. hope this helps.

Master cylinder needs replacing. Dealer told me fluid is leaking and making the traction light come on. Is this true?


if your fluid leak is around brake caliper or wheel cylinder fluid will leak on brake drum or rotor.causing wheel slippage.which will cause traction light to come on.check all four wheels brake calipers and wheel cylinders.look for signs of leaking around the seal area.
