ABS and Brake light come on at intermittent times after I start driving my 2001, 2WD S10. Dealer charged me $50 to check and said a relay in the ABS system was bad. They wanted $1300 to fix it. This problem started around 2004. About six months ago I came across this problem on something I read, and found out it is a COMMON problem with this brake system. Still no recalls. Worst, if you pay the $1300 for the same relay, how long is it going to last?

Abs light and brake light stay on

The ABS light comes on and the abs kick in even when I don't need it making it hard to stop quickly at low speeds.

abs warning light on

ABS system started to come on when easily braking. Then, it finally stopped and the ABS light came on. ABS system no longer works.

The ABS system engages at low speed when normal brake pressure is applied. The brakes are then rendered useless.

abs light on - can't find anyone who can read code - not yet repaired
Turned out that the problem was a shorting ABS sensor in the right front wheel hub. Designed so that you cannot replace just the sensor. I had to replace the entire wheel hub. Problem is fixable, but you should redo the brakes at the same time.

Abs brake control module went out at 138,467.
abs makes nise and the pedle pulls back and braken tinen
While driving the ABS lights on along with the Brake light. Sometimes they are both off during my trip to work and don't come on for a day or two. If its a sensor can it be replaced when new breaks are installed? Or can I replace the sensor by taking off the wheel hub my self?

The ABS and Brake warning lights came on about 12 years ago, and have stayed on ever since. I've successfully ignored them.

I had a 1995 s10 2wheel drive pickup that had this problem.The dealership told me the part was 1400 dollars not counting installing the part.I put black tape over the lights and drove it with manual brakes for years.Then i bought a 2003 s10 with zr2 package(I love the truck) but the abs light comes on with the emergency brake light intermittly and i had to buy a abs code reader to cancel the abs code every time it comes on ?The zr2 is a wonderful vehicle that fits my needs like a .glove.The abs code reader read rear wheel speed sensors were getting erratic readings,so i cleaned up the rust around the sensors and cancelled the code.Then it threw another abs code co265(ebcm relay circuit open) which tells me the EBCM controller is going bad,so i will pull fuse and drive with manual brakes untill i figure out how to solve this problem?Why has GM not had a recall on this by now?This is a very serious driving hazard it needs a recall.

ABS and Brake light came on at 111,200 miles. Diagnosed with ABS sensor which was replaced. Both continue to go on intermittently for the past 8 1/2 years even after re-setting the computer multiple times. Truck now has 208,000 miles. I just know that I will not have ABS capability when lights come on so have been driving it "as is."
ABS light was coming on. I had the light removed.Where are you located so that I can have it fixed or placed on diagnostics?
1999 Chevrolet S10110,000
ABS light came on. breaks grind and I have a hard time stopping unless i pump breaks. Cost of repair is about what I could get for it at a trade in value.
