Once again brake fluid marked as checked and good. The contact also stated that the abs warning light illuminated. Check and see if there is any whining coming from that. Now, the shoes are held on with two small pins, one at the top and the other at the bottom of each shoe. Btw, It's a 2003 2500hd 4x4 6. Barbara answered 2 years ago It's been fixed.
Check the wire connectors to each wheel. The Chevy Tahoe has been a good seller for General Motors over the years, and the manufacturer even came out with a Tahoe Hybrid in 2009, which was one of the first full-size hybrids introduced into the market. I'm not sure why you do not have any codes. All he did was clean the sensors and it was fine since. It sounds too simple but it works.
Remove the sensor, clean the area around the hole it goes into and blow it out with air then replace the sensor. The only codes that it is showing on the reader at the local Oreilly's is mass airflow and knock sensor. The motor can be unplugged from the module and will shut off. The wheel sensors are where I would look next. My sister has a 2000 suburban also with the same issue. It takes about a week.
I feel the dealership did a 'quick-fix'. I am exploring all options right now. The red brake warning light stays off. I have a 2001 Tahoe with approx 240,000miles on it. Just unplug the fuse, you'll maintain traction control and save your battery. Derek answered 4 years ago I'm having some trouble on my 04 saturn vue. Good Luck Glenn answered 6 years ago Mine sometimes comes on when I start the truck, and sometimes when I am moving at constant speeds.
No corrective action has been taken at this time, as I have been researching possible causes of this problem. Could be on just one wheel. The abs light does not illuminate when it happens. They told me that I needed to have the complete system diagnosed for all codes and wires, etc. The manufacturer was not made aware of the failure. Since I got it back however the abs light was coming on and off and the left front brakes would bddddtttt grab and make an awful ffflllllpppp sound and scare me to death. Also a malfunction in the pump, stuck valves and devective accumulators are possible causes.
If a weeering sound happens while driving and increases and decreases with with speed I would definatly suspect wheel bearings. Just assemble in the reverse order and manually adjust the adjuster assembly to where the shoes are snug and you can still get the hub assembly back over the shoes. If a circuit faults it is usually due to a sustantial loss of brake fluid or a leak. Trouble is, the lights had mysteriously gone out and refused to come back on. I know it seems too easy but it works. Remove the disc brake caliper.
Don't hang it on the rubber brake line. Once stopped, turned off truck and pumped brake, the pedal bottomed out, then pumped back to normal and light went off, But will came back on. You can find it by removing the engine cover and reaching back behind the intake manifold and down. Also, sorry he was told his passenger side front seal is leaking in the front differential. There is a possible clue, but I know nothing about it: they found that the emergency brake was not working, and had to have several parts replaced.
Also, if you wrap your cable ends with plastic and protect them good, you can still drive you truck while the part is being worked on. Try it first before going to the dealer or mechanic. There should be a cover over the componant that easily comes off. Or you could pull each wheel, disconnect the bearing harness, hook up a continuity tester to the two leads and spin the bearing. If the pin is missing, the dealership will replace the retaining pin at no cost to the owner. The failure mileage was 180,000.
The electronic brake control module has shorted out internally keeping the anti lock brake motor running. Upon releasing the brake the pedal engaged correctly. That is why it works, but initially had no pulsing. The brake pads are going to wear because of the friction created when applying the brake pedal, and the brake rotors are going to wear for the same reason. In order to change the Brake Light Switch on a 1998 Tahoe you have to do the following. I took the module out of a2002 Sierra and it is engineered with no T10. Then started working, but pedal went to the floor.
Installation is in reverse of the order above. This is annoying and we wonder if the brakes will give out sometime. The pedal to the floor means your losing hydraulic line pressure somewhere. The vehicle was taken to an independent mechanic where the failure was unable to be determined. The vehicle was not taken to the dealer for the failure. The failure had been ongoing since August 2010.
