2009 Nissan altima hybrid reset maintenance display

check the switch make sure its on ---check brake fluid level --- the wiring to the abs make sure no damage or disconnection when brakes/rotors were done ---recheck brake pads if not seated right known to throw codes ---

There is ALWAYS a reason.
Reasons that the ABS light will illuminate:

1. Brake pads, brake shoes, rotors, or drums worn beyond allowable specification;
2. Brake fluid level low, or brake fluid leaking;
3. Failed ABS control unit;
4. Failed ABS sensors at wheels

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.

how much brake fluid did you remove or put brake shoes on wrong reason abs light on.check brake fluid.when replace front brakes you have make sure mastercylinder reservoir corver on then pump brake pedal seat brake shoes against rotor then check brake fluid level.

Brake fluid attracts water, its a good idea to flush and fill the brake fluid regularly.

Master cylinder and/or brake booster could be the problem. A tiny bit of air in the system will effect your braking abilty. A fault in the ABS system would prompt the computer to trigger the ABS light. If you have brake shoes on the rear, make sure they are properly adjusted. Hope this helps.

worn out pads or rotor, possible broken abs cable to brake. first check to see if all 4 are connected. all ore on back side of brake dust shield. than check to see if the brakes are worn last is the rotors. also see if there is a recall on the brake and battery re charge system.

Go back around and check to make sure you didnt accidentally pinch or cut a brake pad sensor. Also the ABS modules on VAG cars are pretty crappy.

possible dirty/defective wheel sensors (typical), or faulty ABS actuator.
