Question about 1993 GMC Yukon
My two door 1993 GMC Yukon always makes a sound similar to an antique car horn or a dog growling. I know those two don't sound the same but it's the best way to explain this sound. It only happens when I begin to drive the truck after each start up. It doesn't happen once the speed builds up. Some suggestions have been the ABS brakes. I don't know if that's true and would love to fix this loud and annoying sound. Is it safe to drive while I am trying to find out what it is? Thanks so much.
Sounds to me you might either have a bad wheel bearing or a bad cv joint.

hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk

I WOULD NOT KEEP DRIVING IT.WHEN ABS LIGHTS AND BRAKE LIGHTS COME ON.YOU HAVE BRAKE FAILURE. TOW IT TO DEALERSHIP HAVE IT SERVICE.AND CHECK THE ABS BRAKES SYSTEM .BECAUSE ABS BRAKE SYSTEM IS NOT A HOME FIX.BECAUSE THE ABS HYDRAULIC MODULATOR UNIT HAS LOWER FROM HOME POSITION .IN ORDER TO MOVE THE MASTER CYLINDER FROM UNIT.YOU NEED A TECH 2 SCANNER TO DO THE JOB.TO GET ABS BRAKES TO BLEED RIGHT BEST TO GET THEM PRESSURE BLEED INSTEAD OF MANUAL BLEEDING GET LESS AIR IN SYSTEM.THAT WHY SEE DEALER SHIP HAS THE THINGS TO DO THE JOB.

try to pull up on your parking brake pedal with your hand when light comes on. if this makes it go out u will need to adjust the parking brake switch under the pedal. or replace pedal spring that holds it up.

you have to fix the problem with ur brakes- first check the wiring ,connectors and connection clips to the abs sensors and modulator if looks ok than have truck scanned some auto stores such as auto zone / advanced auto do it for free the code will give u a start point towards fixing ur problem--visual inspection of brakes doesnt always show problem

If you forced the pads back into the calipers without loosening the bleeders you probably forced gunk into the abs modulator valves. Sometimes doing the automated bleed proceedure (need Tech or Bi Directional Scanner) will bring things back to life.
