Question about 1999 Chevrolet Silverado 1500

98 chev p/u c/K1500 wheel rotor and hub assembly

Driving down the road and lost brakes. Did stop, but extremely hesitant as though I may have lost a caliper. I then took off again, and heard a noise like a bearing, I thought I had a bad bearing in the hub, and thought the wheel was going to fall off. I babied it home and pulled the wheel off, to my surprise the actual portion pf the rotor had seperated from the hub assembly and I could spin the rotor by hand as though the weld bead broke seperating the portion the brakes ride on from the portion that goes through the studs holding the wheel on. Are they two pieces? Did they in deed break?

Front passenger brake is pulsing and there is no abs light on in my 1997 pontiac grand prix.I believe it might be abs sensor but don't know where to find it in wheel assembly.

A front brake pulsing with no ABS light is a rotor that is no longer true i.e warped. Pull off the tire and rotate the rotor. Hold a straight edge (ruler) across the outside of the rotor as your rotating the rotor. You will note that it changes distance on the straight edge / ruler as it rotates. (in out wobble) A good way to test for an out of true rotor is to drive at about 45 miles and hour and really stand on the brakes (do not lock them up) If the steering wheel and or brake pedal pulsate... you most likely have a rotor problem. If your rotor has never been "turned" it is probably time to do so.

The ABS sensor is behind the rotor on the lower control arm pointed outward toward the rotor with a flat button face. You can not see the button face with the rotor installed. If the sensor is bad you will have an ABS light. I think your troubleshooting the wrong problem. i.e rotor vs your current focus of the ABS sensor.

I would like some feed back on the running dynamic on the road brake test.

Thanks for choosing FixYa,

Free, information

If you here a roaring noise in your front wheel and when you turn one way or the other and it stops. then your gonna be looking at changing your wheel bearing ( hub assembly ) , but how do you know which one to change. Well when driving down the road, move steering wheel back and forth easy, which ever way you turn the wheel and the noise stops that is which side is bad.
Example : your driving alone and you turn your wheel to the right and the noise goes away, then it's your right wheel bearing ( hub assembly ).if you turn to the left and the noise stops, then it's your left wheel bearing ( hub assembly ).

Rotors keep warping

Could be a number of problems. Here are a few.

Defective Brake Pads
  • Brake pads that are defective and/or incorrectly installed can, over time, cause brake rotors to warp and become damaged. Brake pads are responsible for squeezing against the spinning brake rotor, an action that causes a vehicle to slow down or stop. If the brake pads are bent, misshapen in any way, or aligned and/or installed abnormally, they can exert abnormal pressure on the brake rotors, a condition that can cause brake rotor warpage over time.

  • Abnormal Brake Caliper Action
  • An abnormal or malfunctioning brake caliper can result in brake rotor warpage if the degree of brake caliper dysfunction is severe enough. A brake caliper houses a set of vehicle brake pads and provides the squeezing force necessary to squeeze the brake pads against the spinning brake rotor. If a brake caliper applies too much pressure to the brake pads, or if it applies pressure inconsistently, it can cause a brake rotor to warp over time. Adequate brake caliper action is necessary for optimizing brake pad and brake rotor function.

  • Excessive Heat
  • A vehicle's braking system generates a tremendous amount of friction-related heat, heat that normally gets radiated away from the brake pads and brake rotor mechanisms. However, in cases where excessive heat is generated within a braking system and not dispersed adequately, serious brake malfunctions can occur, which can include brake rotor warpage. A stuck brake caliper, old, worn-down brake pads, or a defective brake rotor can cause excessive heat to develop in or around a brake rotor, which can cause brake rotor damage and warpage.

  • Damanged Wheel Hub Spindle
  • A brake rotor assembly is supported by and rides on a long, slender metal tube called a hub, or wheel hub assembly. The hub is what allows for the smooth, even circular motion of the spinning brake rotor. Designed with a smooth, low-friction exterior, the wheel hub assembly is critical to the proper spinning motion of the brake rotor. Any abnormalities or defects with the wheel hub assembly, including hub warpage, cracking or misalignment, can cause abnormal brake rotor rotation, which in turn can cause brake rotor warpage over time. Normally, a damaged wheel hub assembly is noticed and remedied prior to extensive brake rotor damage, as a severely damaged wheel hub assembly will cause a vehicle tire to wobble and shake.

    How do you remove the front passenger hub on a 98 escort. I wrenched on the nut, but it won't loosen

    1. Raise and safely support the vehicle.
    2. Remove the wheel and tire assembly.
    3. Unfasten the disc brake caliper retaining bolts.
    4. Remove the disc brake caliper and secure the caliper aside with mechanic's wire. Do not disconnect the brake hose.
    5. Pull the brake rotor from the hub.
    6. Inspect the rotor and refinish or replace, as necessary. If refinishing, the minimum thickness rotor thickness is stamped on the brake rotor.
    7. To install:
    8. Place the brake rotor to the hub. Make sure the mating surfaces are free of rust which may prevent the brake rotor from seating properly.
    9. Remove the mechanic's wire and position the brake caliper.
    10. Install the brake caliper retaining bolts to specification.
    11. Install the wheel and tire assembly.
    12. Lower the vehicle.
    13. Pump the brake pedal several times to position the brake pads before moving the vehicle.
    14. Road test the vehicle and check the brake system for proper operation.
    It sounds like your hub/rotor is froze'll need to apply some penetrant in the lug stud areas as wells as the area where the rotor mates to the axle hub.

    2004 impala vibration when pressing brakes

    hi sounds like a brake pulsation remove the brake rotors and make sure the hub face is clean of rust and the inside of the rotor reassemble the brakes and torque the wheel nuts to 100ft/lbs if it still pulsates then the rotor is warped some aftermarket rotors are warped from sitting on the shelf you can also check the laterial run out of the rotor with a dial indicator if you have one hope this helps

    Replacing the rear rotors on a 2003 E320

    So this is what it takes to replace rear brake rotors on a 2003 Mercedes E320;
    1) open the bonnet (hood) of the car and loosen/remove the cap off of the brake fluid resevior.
    2) remove outer spring clamp from brake assembly (it clips in to the iner edge of the holes of the caliper).
    3)using a 7 MM allen wrench, remove the brake caliper.
    4) using 18 MM box wrench, remove the caliper housing assembly off of the wheel hub.
    5) using a star wrench, unscrew the rotor locking screw from the rotor
    6) squirt some liquid wrench on the rotor hub and knock the rotor with a hammer to work the liquid wrench in.
    7) using the same hammer, knock the rotor off the hub.
    8) using a metal file, lightly file old residue off of the hub and place the new rotor on the hub.
    9) set the hub by screwing in the lug nuts and then screw in the hub locking screw using the star wrench, then remove the lug nuts.
    10) reinstall the caliper housing assembly onto the wheel hub using the 18 MM box wrench.
    11) push back the brake claiper piston to its home position and install the inner brake pad (the one with the snap clips)
    12) insert the outer brake pad in the claper housing assembly.
    13) slide on the caliper housing with the inner brake pad in place (over the outer brake pad) and screw in the caliper screw rods using the 7 MM allen wrench
    14) on the right wheel brakes, DO NOT FORGET to slide in the brake sensor (the one with the black connector) and connect it to the connector on the caliper housing.
    15) be sure to reinsert the spring clamp onto the outer brake assembly to set the assembly squarely onto the wheel (there should be no wiggle in the brake assembly after the spring clamps are installed).
    16) finally mount the wheels.
    17) you can bleed the brakes at this point to release any trapped air (which is unlikely) but be sure to pump the brakes after starting the car BUT BEFORE MOVING IT to re-preassurize the brake system before driving the car.
    17) ONE WEEK LATER - recheck brake assembly to ensure all is okay and brake fluid.

    This proposed solution is for a 2003 Mercedes Benz E320 and NOT a 2005 model as stated by the limited option selection provided by when initially describing the problem.
