This is a (4) four wheel sensor system and more than likely one of them has failed. This will cause ABS module to turn on warning lamp and make the brake pedal 'act up' under the right conditions.This 'acting up' is the ABS system getting a false signal that a wheel is not turning the same as the others when it actually is. Have it scanned for codes and a streaming data scan on a road test under the same conditions that you are experiencing the 'act up' to pinpoint the fault. Hope this helps! Please rate me.

How thick is the lining on a new brake shoe


Lining thickness is dependent on a few factors. A. Is your lining bonded to the shoe or pad, or is it Rivited to the shoe or pad? B. What is the application? Lining thickness is determined ultimatley by the manufacturer. Generally speaking on Automotive and light truck applications new lining for brake shoes is between 6/32nds and 12/32nds of an inch. Add a couple 32nds if rivited. On front brake pads the lining is much thicker when new. On average a new brake pad can have lining between 10/32nds to 18/32nds. Pads are in need of replacement when bonded lining has worn to 2/32nd and rivited lining has worn to 3/32nds since the rivet head can come in contact with the disc brake rotor or drum at 1/32nds. Lining can also break free from the pad or shoe when they get that low due to rotor or drum out-of-round. This can cause lining to break free from the pad or shoe and cause dmage to the drum or rotor surface. When replacing brakes, its always good to have drums or rotors machined or replaced. For rotors, there are three specs to take into consideration. 1. Minimium machining thickness. If rotors are machined beyond their reccomended minimium machining they will warp due to heat. This warping will eventually lead to brake pedal pulsation. 2. Run-out; Run-out is measured using a dial micrometer and usually .003 to .005 of an inch is considered excessive. 3. Material Thickness Variation; or parralleism is measure with a micrometer. .0003 to .0005 ten thousandths of an inch is considered excessive. It is extremly hard to find a rotor that will pass all three of these measurements. If someone tells you the rotors do not need to be machined because they "look good", don't trust them because they don't know what they are talking about. Rotor condition can not be determined by the human eye. Drums have a maximium diameter they can not exceed, as well as an out-of-round specification as well. A good brake job will always have drums and rotors either machined or replaced. Money can be saved if they can be machined as it it cheaper to machine than replace.

I have 2002 chrysler grand voyager 3.3 litre auto. abs light came on and is gone now , but there is a lot of vibration and rattle when i press brake. What do i do?


Inspect both the front and rear brakes. Including rotors, drums( if equipped in rear), abs sensors and wiring to the sensors, and brake pads/shoes. Also be sure to remove the calipers and look at the brake pads to check for worn out or uneven wear and replace if necessary. Hope this helps

1999 Chevy Tahoe- Soft Brake Pedal


Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

Brake pedal vibrates while braking and doesent stop right away


There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

1999 Chevy tahoe 2dr Brake shudder intermitant hard pedal.


You probably need to surface the rotors and the drums. I have gotten brand new rotors that were so warped that they were below min. thickness (not kidding) after surfacing them. Needless to say, they went back to the parts store. So now I surface every new rotor that I install. Happens to rotors way more than drums, but have hade a couple of drums that were warped when new so I check them before installing them. Good luck. Hope this helps.

Low brake pedal


You may have a bad brake Booster and it could have brake fluid in it.
Also you may want to try a complete brake fluid flush.
