Yes and No. When ABS get activated it gives a pulsation of fluid pressure to that wheel it detect through the sensor that is at lock up. It prevents brake lock up and keeps you straight with the ability to steer. If you are smelling brakes you need to check the pad a caliper can stick or even a binding rear wheel cylinder.

What is a abs modular on a Escalade Cadillac?


Jesse, The module will not stop fluid to rear brakes, a bad master cylinder will,leaking lines, air in brake system, faulty metering block if equipped, collapsed flex lines or pinched brake line faulty caliper or brake cylinders,etc. will cause the possible feeling of no rear brakes.
(ABS Module components) the ABS speed sensors and the ABS control module . When the brake is applied, the ABS control module reads the speed data from the speed sensor and sends the correct pressure to each wheel to prevent any wheel lock up, eg. sliding/skidding Links below have more info.

ABS/ESC lights on.


It depends on what type of brake system your vehicle has. disc all four wheel or front disc and rear drum . when the abs light is ON its a wheel sensor problem which is located near the wheel hub.

1998 Dodge Dakota, the brake light and ABS lights are on with brake pedal pushed and the rear wheels continue to spin.


check the rear wheel sensor wires and sensors . IT appears that the ABS is receiving ( or not receiving a signal telling the unit that the wheels spinning) a bad signal saying that the wheels are stopped and so the fluid to the wheels is restricted to allow them to spin. Check the fluid level in the reservoir as there may be no oil in the section of the master cylinder for the rear wheels and that half is not working

I replaced the brake master cylinder on my 91 Lincoln Mark 7 with a non high pressure master cylinder and the rear brakes do not hold. Do I need to change the cal. on the rear also?


ANTI-LOCK BRAKE SYSTEM (and HCU-Hydraulic Control Unit)
General Information The 4-Wheel Anti-lock Brake System (ABS) is an electronically operated, all wheel brake control system. Major components include the power brake booster, master cylinder, the wheel speed sensors, and the Hydraulic Control Unit (HCU) which contains the control module, a relay, and the pressure control valves. The system is designed to ****** wheel lockup during periods of high wheel slip when braking. Retarding wheel lockup is accomplished by modulating fluid pressure to the wheel brake units. When the control module detects a variation in voltage across the wheel speed sensors, the ABS is activated. The control module opens and closes various valves located inside the HCU. These valves, called dump and isolation valves, modulate the hydraulic pressure to the wheels by applying and venting the pressure to the brake fluid circuits. Some models are equipped with a Traction Assist (TA) system. The TA system senses wheel spin upon acceleration, turns on the Hydraulic Control Unit (HCU) pump and applies fluid pressure to the appropriate rear wheel. Two additional isolation valves in the HCU will also close to permit fluid to flow only to the rear wheels. The TA system monitors TA usage to avoid overheating the rear brakes. If the system does sense brake overheating, the ABS module will inhibit TA operation until the rear brakes are permitted to cool down.

SYSTEM COMPONENTS The anti-lock brake system consists of the following components:
  • Vacuum booster and master cylinder assembly
  • Hydraulic Control Unit (HCU)
  • ABS module
  • Wheel sensors
  • Pedal travel switch

On 1992-1994 and 1995-00 a scanner is used to perform the brake bleed. But on yours, I think it's different according to the manual.

What do you mean change the cal. on the rear also? Do you mean Caliper?

I have a 95 mercury sable and a little while back our abs light came on well the finances werent there at the time to have it checked so now i had to change the complete brake system on the drivers rear....


Your master cylinder (rear) check valve has failed;
(the pressure is not being released when the brake pedal is not pressed and, the brakes stay applied)
replace the whole master cylinder.
As for your ABS clean the ring on the wheel that is "seen" by the sensor clean it too; it looks like and, works like a old phonograph speed ring (the sensor reads the flashes as the wheel turns to assertain the vehicle's speed.)

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...

My abs light stays on 1995 chevy G20 van and have to replace front brakes every 6 months but rear brakes show no wear and are atleast 3 yrs old. On slick pavement right front brake sometimes locks when...


I'd be checking the sensor (ABS) at that wheel, (right front) and adjusting rear brakes to proper clearance, as well as inspect them for proper operation with wheels off.

Antilock brakes not funtioning properly on "hard" stops


Yes, I never did like ABS brakes because of this. What you have experienced is the ABS system working as it is designed to do. I know, it doesn't seem like you should still be moving after slamming on the brakes, but here is how it works;
When you apply a fast and hard pedal and the ground beneath you is wet the wheels stop at different times. There are sprockets mounted to the rear of the rotors, with magnetic sensors that monitor the wheel info. for all four wheels mounted next to the brake calipers. On a hard stop when the sensor detects one wheel stopping and another still going, these sensors send "pulses" to each wheel until the vehicle has stopped without the brakes having to lock up. The pulsiing is what you experienced and is a normal part of the ABS function.
Please rate this and let me know if it helped.

Vehicle shakes


I doubt it. You'd have an ABS light on. All wheel are warm to scalding hot after even light driving. ABS systems do not apply brakes. They unapply them. They simply cut the fluid to one of the wheels / axle sets of brakes. (Newer stability control systems use the brakes) In your case. The ABS can deactivate either front wheel independantly, or the both the rear brakes together. You can take the wheel off & flip the pad & piston up to check it if you want, but I wouldn't think it was the brake dragging at the top of my list, no.
