Pulsating brake pedal indicates that the ABS is active under brakes whether it is required or not
from the rest I would first have a fault scan done to find any faulty sensors
Try replacing the ECM with a known good unit as the scan fault readings may reveal a problem ECM

That sounds like a bad charging system. Auto zone can check your alternator and battery in your vehicle. EVERYTHING in that need electricity. when it starts getting low weird things start happening.

Testimonial: "I did feel something today, tried it out again today for a drive to see if it still does it and now I feel the altantor is losing power when I push the breaks to stop ?"

    Did you get your problem fixed ? My car did the same thing and every mechanic said it was an engine problem. Sure feels like it but it's not! It's a simple fix and I'm a girl and I did it myself. It's more than likely a sensor wire harness needs to be replace. Just so you know it's not your master cylinder or your alternator is not your abs it's a broken harness wire from the engine down to the connection behind tire to the abs.

My 2004 Pontiac aztek runs great unless you have to go up a hill or pass someone on the highway. Three different mechanics including the dealership can't figure this out. When u accelerate more than...

Loss of power at highway speed is usually clogged fuel filter or clogged air filter. Checking fuel pressure won't tell you if the filter is clogging up. You can still have pressure, just no volume. Air filters can do the same, except it will usually die or stumble coming to stops. The abs and disable light won't affect the engine performance. Hopefully you have a bad wheel sensor that is also disabling the AWD. The sensor is around $100 the actuator for the AWD is over $300

Pulsating brakes and peddle pushing back up

This is a classic ABS problem. Either the pump or the ABS controller. But as it is causing the brake pedal to push back you should get it seen by a qualified mechanic and DON'T drive it until it is fixed.

Traction control light flashes and abs activates, slows car down, pulsates car

I would take it to someone who has a code reader, or to a dealer, I would not trust the vehicle for very far or very fast if you did have to drive it to where it will be worked on. It may even be safer to have it put on a rollback wrecker and taken to the shop.I don't like to make suggestions of driving a vehicle when it pertains to the braking system. I hope I have been of some assistance.

ABS problem with GMC 2002 Sierra

its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

ABS brakes not working

If you can feel the pedal pulsating and the light turns on the Abs is doin its job. if you want a better stop you could try a brake pad upgrade to ceramic pads and for even more stoping power add an after market drilled and sloted rotors.

Bearings bad, grinding when I hit the breaks,petal pulsating

when your bearings start going bad two things happen first the ring gear that the abs reads the wheel speed moves to where it doesnt get a reading so that would probly be the abs light and second the flexing in the rotor will tend to colapse the brake piston leaving extra gap between the piston and the brake pad you might be able to confirm this by doing small short pumps and see if the pedal improves and it stops better i suggest replacing the bearings in pairs if you continue to drive the vehicle you run the chance of ruining the calipers hope this helps

Breaks pulsing

Does the abs light come on when pulsating? if yes then maybe you have a bad ABS sensor or it just the sensors cleaned . Where they turned under spec .which means more likely to heat up and warp or crack

The brake light and ABS light have come on at the same time and my break peddle feels mushy i have to push all the way down to stop.

How does the Brake Fluid Level Look? You need to get the Brake System Bled and Could also need to Replace your Pads.

Or you could just pull the fuse for the abs and not have abs but you won't wreck from pulsating pedal.
