Brake and ABS lights when braking

Brake and ABS lights when braking - 12/08/07 04:10 AM

The last few weeks I've noticed that my brake warning and ABS warning lights in the instrument cluster come on when I brake, especially when going down hill. At first it happened only once a day ... then two or three times ... now almost every time. I don't see or feel a problem with the brakes and how they act - no odd sounds, no sign of action from the ABS system. Everything seems to be normal, except for the warning lights.

Anybody have any ideas?

Low brake fluid in the reservoir? The sensors is at the back if I remember right, so when you go down hill and brake the fluid would be lower than the sensor!

just a shot in the dark!

what iron said, also check around your drums and stuff to see if you have a leak which could be causing it.

i have a crapped out wheel cylinder in the back of mine and it is causing this to happen.

Your anti lock sensors could need to be leaned, The reason I have a Sportage is the sensors on our Grand-am GT was dirty but I thought I had a bigger problem so I traded it in stead of fixing it. The Grand-am was faster but the Kia is funner off road, with the Grand-am I always had to walk around in Moab now I can drive. Maybe that why I'm getting fatter. <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />

Don't know why I didn't think of this yesterday!

Just had the rear axel bearings and oil seals changed on my Sporty, First I don't have ABS, I had taken her in to the local tyre/brake shop because on ice one rear wheel would lock up, and remain locked after you release the brake, not a good thing on ice and snow.

Turned out to be a leaky axel oil seal, causing oil to cover one set of rear brakes. now if you had ABS the sensor might either get contaminated, or the ecm might get confussed with the signals the ABS sensors are sending it, one wheel turning faster than the other, and trigger the ABS warning light, but the ABS system might compensate for the lack of braking on one side and you might not notice it as much as you would without ABS!

Just a theory!

p.s. if it is the oil seal get it from NAPA and not the dealer, it's about $130 cheaper! :P
