ABS brakes do pulse. If that is not what you are detecting you can get the error codes. Many Auto parts stores will have loaner meters for free. Cadillacs have lots of sensors.
Anti-lock brakes have sensors to control braking which could be the problem.

If this car has a StabiliTrak chassis then it will have a continuously variable road-sensing suspension with a fast-acting variable dampers, integrated rotary sensors to measure body and wheel positional changes due to varying road conditions.

This car does have recalls you can check.

Last resaults try changing all the break fluid get it done right with the BG44 PROFESIONALS Problem: Brake fluid becomes oxidized and contaminated over time and use. Heat and moisture cause corrosion on parts and brake fluid failure. This causes a spongy brake pedal and shows up in discolored brake fluid. Solution: The entire brake system is inspected for leaks, master cylinder corrosion, worn pneumatic parts, harmful varnish build-up, broken or rusted bleeder valves, worn rotors and drums and air in the brake lines. All old brake fluid is replaced with BG Heavy Duty DOT 3 or DOT 4 Brake Fluid. The result will be a longer lasting, more efficient and safer braking system. http://www.bgfindashop.com/bgservices/brake.htm

My 2004 LeSabre shakes bad when I brake at around 50 mph. I changed the front brake pads. How difficult is it to change the front rotors?


Actually, changing the front rotors is not that difficult and they are relatively in-expensive. Anytime you change the pads on the front of your vehicle i would recommend having the rotors resurfaced or replaced. Especially if you are getting a brake pedal pulse when applying the brakes. Here is a step by step guide that will help you in removing your Front rotors.

Rear brake rotor noise


warp rotors tend to make noise at low or high speeds depending on the degree or how badly warped they are, if the brake pedal kick back when you apply the brake then you will have to get new rotors installed

When i hit the brakes or go over 60 miles the wheels will start to shake


It sounds like you may have more than one problem here. First I would investigate Front End Alignment and ALL Steering/Suspension components for excessive wear and/or looseness. Second I would Inspect the Brake Rotors and Pads for uneven wear. Third I would check the Tires for uneven wear and balance. Many things can cause these symptoms: Worn out Ball Joints, defective Shock Absorbers/Struts. Worn out Tie Rod Ends, Idler Arm, even the Steering Gear Box can be part of the problem. Brake Rotors and Tires can be out of Balance with either one causing the problem over 60 MPH. I strongly suggest having your vehicle inspected by an ASE Certified Front End and Brake specialist immediately. It is very dangerous to drive a vehicle with these symptoms.

Brakesa are jumping when brakes are applied


i do believe you mean the service brakes, and when pushing the brake pedal the truck shakes?

Pad transfer will cause uneven brake discs with humps on em. Every time you then step on the brake pedal you'll feel the pads going over the humps, causing the shakes.

The best way to get rid of this is to replace the disc brakes with new discs.
Remember to change the pads too.

Shake/Shudder while depressing the brake.


I just changed the brake pads and rotors on my father's 2001 Trooper that he recently purchased because they were shaking just like your were.  He bought it from a mechanic shop and they had put new pads on it but it needed new rotors as well.  If there is noticable groving on the rotors and new pads are installed it can create shaking, sometimes severe, when the brakes are applied.  It sounds like this is what has happened with your vehicle as well.  That being said, I don't consider it a huge safety issue to drive it until you get it fixed, just know that your braking will not be optimal and that it will take you longer to stop than if the brakes were working properly.  All that being said, get them fixed ASAP so you don't have to worry about it.  Who wants to mess with safety right?  Good luck, hope this helps!

1998 Camry steering wheel shakes when braking and over 50mph


if you hit the brakes and it shakes its your rotors, they're probably warped. Having them turned (polished) won't fix it. You'll have to replace them. As for the shaking at over 50, if you're not touching the brakes, you'll probably just need to have your tires balanced. Maybe jack up you car an check the ball joints and tie rod ends (keep the tire on and see if there is play, either up and down (ball joints) and left and right (tie rods)). Hope this helps.

Shakes heavily when braking over 50 mph.


The shaking would be from your front rotors. First, loosen the lugs and retighten them with a torque wrench (not an impact gun) to the proper setting as described by Toyota. If the lugs are tightened unevenly or too tightly, it will artifically warp your rotors. If this does not fix the issue, your rotors are most likely warped from overheating, or being sprayed with water while hot, or from age. Get new rotors (and pads - always use new pads with new rotors), install them, and torque your wheels properly, and you should be in good shape.
