It doesn't need a reset, a mechanic needs to scan for the fault code that is setting the warning light. It could be a poor or no connection at the wheel speed sensor or a problem with the ABS.

SOURCE: 2002 Suburban ABS System Brake Light

I have had this same problem on two difference vehicles both of which are suburbans.

The solution is simple.
Remove the engine cover.
Locate a small ground wire that is bolted to the top rear of the engine block on the passenger side.
Remove the bolt, clean surfaces and replace.

This should solve your problem.

I know it seems too easy but it works.

SOURCE: Remove service brake system display from dashboard?

Check ABS system for codes. I have an '03 Silverado and have a faulty EBCM( Electronic Brake Control Module, "ABS module"). Can't reset anything. Only replacement of EBCM will fix it. Incidentally, if you have to replace it, you can check on Ebay for a rebuilt unit. You shouldn't have an issue with your "base" braking system though, if this is the case. ABS is electronically controlled and with or without it, your brakes will still function. I hope this helps.

SOURCE: Front brakes shudder a fair bit when braking

It seems now a days that everyone loves to turn rotors, the only reason to turn a rotor is if it is running out, what this means is that
it is moving back and forth and not in a straight line. What a brake tec is suppose to do is place a dial caliper on the rotor and spin it and see if it is running out,if it is then it must be turned,as long as the rotor is not under the mfg min width. Any vibration,pulsing,shudder,
would tell me that it needs to be turned, just wanted to explain the reason behind it. Any other questions please post back as everyone is more than happy to help.

SOURCE: i have a 2005 chevy equinox i replace the front

check the connections on the abs, behind the rotor by strut is the connection for the abs if the connector is loose or not properly affixed to the clip it sets off the abs trouble code or low speed saftey usually activates at slow speed under 5 miles an hour the connector and clip are part of the abs circuit--also recheck ur brake pads for binding and brake fluid level --if u get a trouble code have vehicle scanned some auo stores such as auto zone / advanced auto scan for free this will tell u which sensor or unit is causing problem

SOURCE: Service Traction System Light on 2003 Chev Impala

on the rotors you probably noticed two lines one for the brakes and the other is your traction control magnet which picks up a signal to tell the computer to control the braking system when the wheel locks up in hard braking, you either damaged the magnet or it picked up some metal shaving while replacing the brake pads

What could be the problem when I aply brakes pedal gets real hard where car wont stop when braking coming to a stop brk. light and abs lights on


Hey Joes, 1 problem at a time ,if brake light is coming on that is in the proportion valve ,did you have to push reset button to make light go out,? if the ABS lite is coming on what you can do to check and see if that is the problem is unplug it and try brakes ,it will deactivate ABS and give you normal braking and ABS light will be on ,see if symptyms change , also did you reset ABS sensors to the tone wheel when you replaced rotors ? I don't know what you have and I have seen some cars need a importaint reset procedure for abs to work properly. good luck I hope I gave you some good things to look at that help you.

My 2008 Nissan Altima 40,000miles needs new brakes in the front, according to the dealership. Does this mean I need new brake pads? The dealership also said the brake system fluid was dirty and cont


Yes, it's typical for any vehicle to have the front brake pads and rotors replaced at 40,000 miles or less. A complete service would involve (2) new front brake rotors, (1 set) of new front brake pads (this includes 4 pads), brake fluid, silicone brake grease for the slide pins and possibly new slide pins (If they're corroded) and rubber seals for the slide pins. Because of the age of your vehicle, it's always a good idea to have the brake fluid changed (This means that your mechanic should bleed the brake system by opening the bleed screw on all (4) brake calipers). Brake fluid absorbs moisture over time and will start to break down (Lower the boiling point) and cause rust inside the system making your brakes less effective. Look at the brake fluid reservoir under the hood. The fluid should appear either clear (Perfectly clean) or slightly yellowish. If it appears to be light to dark brown, it's time to change it. If I were you, I would shop around for prices at other reputable service shops. Your dealer is going to charge you top dollar for this service. Hope this helps.

Hey I have a 98 volvo v90 wagon. I replaced rotors pads calipers and hoses from brake lines to calipers on the front. Now my abs light is on and when I brake only sometimes I can feel the brakes pulsating....


Hey man The ABS light is most likely a speed sensor out of range. It will not effect normal braking function. You have already spent a ton of money. Chasing an ABS light fault is not cost effective and you wont feel the difference. ABS problems are a dealer only option(expensive). Take that ABS bulb out of the dash and forget about it.

I have had my driver's side front wheel bearing changed twice and still have issues with the ABS light coming on sporadically and hearing the noise when turning sporadically. I just had the master cylinder...


Sometimes moisture can get into the connectors and short out the system giving it an error. Mine was in the passenger compartment under the seat. Sprayed it out, cleaned it up and light went out. I just kept up on the brake maintenance, fluid level, pad and rotors more so than average. In all honesty, the brakes received horrible marks in that vehicle's reviews. With the light on I took it to a shop because I have no ABS tools, they could not tell me what was wrong with the system other than the light was on.

My car camry 2003 runs well usually but sometimes the car trembles or gives trembling noise when the brake is applied.


will try to help.your front brakes and rotors may need replacement. when you apply brakes say,at 40 mph do you feel vibration on brake pedal or shaking in steering wheel? the vibration comes from worn or warped front brake rotors. while you have those rotors replaced,go ahead and have new front brakes applied also,or else you'll still have brake problems.always ask to see old parts when you have brakes and rotors unless you have a complety trustable mechanic! the rotors will be round and silver,a very bad brake rotor will have grooves cut in it.always shop for best price at different shops to get a picture of the price for replacement! do not be afraid to ask questions! front brake pads can cost anywhere fron $20.00 to $45.00 rotors can cost $40.00 to $50.00 each there will only be 2 rotors on the front and the brakes are complete for the front,both sides,on the front. as a general rule you'll replace your front brakes twice before you'll need to replace the back brakes because most of you stopping power comes from the front brakes. and as always,if you need further assistance please contact an expert!thank you for choosing fixya.com

How can I change the rotors and brakes on a 2006 Cadillac?


Front brake
Step 1: Identify Front Disc Brake Components
brake_pads_rotor.jpg
Front Wheel Drive Brake Assembly
Most front disc brake components include: brake rotor, brake pads, brake caliper, caliper mount and brake flex hose. Brake service usual occurs between 20,000 and 40,000 miles depending on driver habits, road conditions and brake pad/ rotor materials used.
Step 2: Remove Brake Caliper to Replace Pads
brake_pad_set.jpg
Removing Brake Caliper Mounting Bolts
Locate primary caliper mounting bolts; apply wrench pressure counter-clockwise (When looking at the head of the bolt) to remove the bolts, upper and lower. Make sure the bolt threads are in good shape and replace if necessary.
Step 3: Remove Front Brake Caliper
remove_brake_caliper.jpg
Remove Front Brake Caliper
After removing the primary caliper mounting bolts lift the brake caliper off of the rotor and then tie or secure to the side, being careful not to bend or kink the brake caliper flex hose. Thoroughly inspect brake caliper and brake hoses for leakage, cracks or chaffing and replace as needed. Next remove the brake pads (If not mounted in the caliper) and secondary caliper mounting bolts. Notice how great protective gloves work, most technicians use them on the job today.
Step 4: Remove Brake Pads
remove_brake_pads.jpg
Remove Front Brake Pads
Once the brake pads have been removed, make sure if there is anti rattle hardware to transfer to the new brake pads. Some brake pad manufacturers will include the proper lube (Caliper slides) and anti-rattle hardware to ensure proper performance of their product.
Step 5: Remove Caliper Mount
remove_brake_pads_holder.jpg
Remove Caliper Mount Bracket
Finish removing secondary caliper mount bolts and remove caliper mount. Note: clean and lube caliper slides and pad friction surfaces of all foreign material or build-up.
Step 6: Remove Brake Rotor
brake_rotor.jpg
Remove Brake Rotor
With the caliper mount out of the way you can now remove the brake rotor. Sometimes it can get stuck so you may need to tap it with a hammer or use penetrating oil to free it up. Some manufacturers use small screws to hold the rotor on as well. Clean and inspect wheel studs, replace if any are damaged. Also clean bearing hub rotor mount surface to ensure the proper mounting of the new brake rotor. Inspect the ABS sensor wheel for cracks or damage and replace as needed.
Step 7: Depressing the Brake Caliper
compress_caliper.jpg
Resetting Brake Caliper
To install the new brake pads you must retract the brake caliper piston. Remove the master cylinder lid or open the brake caliper bleeder screw to allow excess brake fluid to be released if necessary. Install C clamp tool and gently tighten clamp until caliper piston is fully depressed. Note: use old brake pad to protect the caliper piston. Close the bleeders once the piston is retracted completely
Step 8: Installing New Brake Rotor
new_brake_rotor.jpg
Install Brake Rotor
Install new brake rotor, the new rotor is manufactured with a protective film over the rotor to keep it from rusting, remove protective film with brake cleaner before installing; also after the brake job is complete you may experience a small amount of smoke from the rotor when first used. This is normal and will go away after the first couple of uses.
Step 9: Installing New Front Brake Pads
new_brake_pads.jpg
Installing New Brake Pads
Reinstall the front brake caliper mount, and then install front brake pads. Make sure the pads are seated properly in the caliper mount; it must be a close fit to work properly..
Step 10: Reinstall Front Brake Caliper
front_brake_rotor_pads.jpg
Re-Install front Bake Caliper
Reinstall front brake caliper and reinstall caliper-mounting bolts, recheck all mounts and mounting bolts. Check the caliper slides to be sure there is no bind and that the caliper moves freely back and forth on the caliper slides. Bleed brake system per manufacturer's specifications to relieve any air trapped in the system. Before driving the vehicle, push the brake pedal down and let it up slowly, repeat until normal brake pedal operation resumes, this operation is forcing the brake pads to travel to the brake rotors.

The brakes, when pressed in the front, seem to not stop and slide , brake lights will not come on, transmission shift makes noise when shifting from park to driveand to reverse. I have taken my vehicle...


Brakes - most common is brake pads were replaced with non-OEM pads and/or rotors were machined during the brake service. Use OEM brakes pads and replace, instead of machining, rotors. Again, use OEM parts for best results. GM recommends replacing rotors during brake service on that model, similar to European models. Unfortunately, GM has not priced the rotors as the Europeans have priced theirs.
Transmission noise - I am assuming a "clunk" noise when shifted while at a stop, also known as "garage shift". Most common is the bushings in the rear differential housing mounts. They may look OK upon inspection but when removed they will be split. Second common is similar issue with transmission mount itself, although that is quite rare.
Brake lights - Any competent automotive electrical repair facility should be able to diagnose this as there is an open in the circuit somewhere. That system is relatively simple and stratagy based diagnosis should lead the technician to the problem.

2004 Mini CooperS- brake service light stays on


Did they replace the brake pad wear sensor? If so, try leaving the key in the on postion for 30-45 seconds (dont start the car) This is how we reset the lights on BMW's and the Mini's use a similar system for service lights
