SOURCE: pulsation in brake pedal and rear end hops during braking

What happens is if you have a bad front wheel bearing when you brake that wheel will turn in or out,when this happens it throws the four wheel alignment out and since this is a solid rear axle,it's forcing it to flex on the suspension,wich could cause the rear tires to bite on the outside edge of one tire and the inside edge of the other,thats one possible the other would be that the rear brakes are are not slowing the wheels evenly causing the same issue.I saw this problem with a bad front wheel bearing on a Nissan Pathfinder but not as pronouced due to the independent rear suspension. Check the front wheel bearings,which of course will mean getting the calipers off the rotors,and then check for any movement in the rotor,if there is check the hub nut,if it's loose tighten it and check for play in the rotor if there is still play that's going to be caused by a bad bearing.You can check the braking in the rear with a simple spring scale(like the ones used for fishing),with the wheels removed have someone apply enough pedal pressure to just engage the brakes but still allow movement attach the scale hook to a wheel stud and pull until it starts to move and note how many pounds of pressure it takes to move the hub.If it's uneven chech your adjusters and even them if needed and then retest,if still uneven you'll need to bleed them again.As far as the dark black substance in the fluid I would say you may gotten a contaminent in the fluid.Brake fluid gets kind of a rusty reddish residue when it breaks down.If I missed anything or you need clarification don't hesitate to ask I'm home all day.Hope this helps solve your problem.

SOURCE: 1999 Chevy Tahoe- Soft Brake Pedal

Try having the dealer flush and bleed your system. It is very hard to bleed ABS systems yourself and have safe brakes that still work afterward. Bleeding non-ABS brakes yourself is easy not the same for ABS brakes. Valving, sensors and what-not require a tech and the correct equipment in my opinion. You do it wrong and you could ruin your ABS system. Do that and see if they firm up. I replaced my brake shoes/pads at the same time all new everything in back, drums/springs everything and new rotors up front. then I had the chevy dealer flush, refill and bleed system. Stiffer pedal and brakes work better. Keep in mind the brakes on 99 Tahoes are inaedequate, require new rotors often, heat up and fade/glaze pads regularly. I replace my pads long before they wear down because they glaze up and start fading early. I'll rough em up once maybe, next time, new ones. Every two brake jobs, new rotors for me. Just how it is. They will stiffen a bit and work better but they will never be awesome brakes. Just how it is on 99 and earlier Tahoes. Hope it helps. Very important to bleed correctly though. I'll bleed my 83 Toyota 4x4 myself but not the Tahoe.

try bleeding your ABS block first, if that doesn not work could need a master or proportioning vavle. Some scan tools are capable of bleeding the ABS system on some vehicles, and some you have to bleed manually.

I am trying to replace the rear drivers side wheel bearing and hub assembly combined. I have having problems removing the hub assembly already on the car. What do i need to do to fix this problem


Remove offending wheel and set park brake extremely tight. Remove brake pads from caliper, and then unbolt caliper. Release the park brake. Unbolt the heater supply tube. Remove six 8mm hex bolts on the CV joint near the transmission. Remove axle. Remove four bolts on outside of housing that hold the 2 bearing race retainers. Reinstall new bearing into the housing... again this will require the EBS tool, and of course you'll have to rearrange the parts of the tool. Once the new bearing is installed, reinstall the bearing race retainers and the four screws that hold the retainers. Carefully reinstall the axle, making sure not to push the hub out of the bearing again.Reinstall six 8mm hex bolts holding the CV joint to the transmission. Reinstall rotor then set parking brake extremely tight.Reinstall brake caliper andl brake pads. Reinstall heater supply tube and wheel, torque wheel bolts to 96 ft-lbs, re-install transmission cover and suspension cover.

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 to change CV joint mazda 323 mod 1991


    In order to change the cv joint, you will need to remove the wheel and the brake caliper and rotor. Raise vehicle on jack stands. Remove the wheel and remove the brake pads and caliper. Tie the caliper up out of the way, do not disconnect the brake line attached. Once the caliper is removed, slide the rotor off. Using the correct size socket, remove the nut in center of hub. Some vehicles have a kotter pin in the shaft just in front of nut. If so, remove pin before nut. Next, you will need to loosen a few bolts that hold the strut to the hub assembly. Once you have hub free from strut, turn the hub either left or right while having someone push in on the cv joint while turning joint left or right. Doing so will allow the joint to slide out of hub. Next, using a pry bar, insert between end of transaxle and transmission and pry out. To install new axle, align the axle with transmission and slide into transmission. Carefully work the other end of axle into the center of the hub assembly. Once you have it in the hub, tap gently with a rubber mallet until you hear it "pop" into transmission. Once it is in transmission, replace the bolts connecting the hub to strut. Replace nut on center or cv joint and tighten just until it seats against the hub...do not overtighten. Replace kotter pin with new pin. Slide the rotor over the studs, replace caliper and brake pads, install wheel and you are done.

    Noise coming from front brakes or wheel ,i change brake pads


    Did you have the rotors turned? Did you check for rotor runout? Did you remove all rust from hub face and rotor mounting surface? Did you remove rust from caliper or pad slides? Lube all caliper and pad sliding surfaces? Are the pads application specific? Did you flush and bleed the fluid? Did you torque the wheels properly?

    How to remove rear brakes on 2001 dodge caravan


    Things You'll Need:
    • Floor jack Jack stand Wheel chock 1/2-inch drive breaking bar 1/2-inch drive socket set 1/2-inch drive ratchet C-clamp Bungee cord Flathead screwdriver Ball peen hammer Handheld portable propane torch (optional) Medium grade sand paper or emery cloth Anti-seize lubricant.
    STEPS TO REPLACE REAR BRAKES
    1. Park the Dodge Caravan on a level paved or concrete surface.2
    2. Place a wheel chock in front of one of the front tires.3
    3. Break the lug nuts loose on the reartires.4
    4. Lift one side of the rear axle of theCaravan using the floor jack and place a jack stand under the rear axle.5
    5. Remove the lug nuts and tire.6
    6. Remove the caliper bolts using the ratchet and a socket. Remove the pads from the caliper starting with the outboard pad and pry it from the caliper housing with a flathead screwdriver. Remove the inboard pad and compress the piston of the caliper in using the C-clamp. Replace the pads. Hang the caliper to the frame using the bungee cord.
    7. Remove the caliper anchor bolts using the ratchet and a socket.8
    8. Remove any retaining rings on the hub of the rotor around the studs. Pry them off with the screwdriver and discard them. You will not need them for reinstallation.
    9. Strike the fin of the rotor on the edge using the ball peen hammer. Spin the rotor and strike it often and from the inside of the tire well moving out. Use as much force as necessary. If the rotor still does not want to come off (rare cases) light up the portable propane torch and apply a liberal amount of heat to the hub of rotor around the lug studs and strike with the hammer to shock it from the hub.0Sand down the hub facing with a medium grade sandpaper or emery cloth once the rotor has been removed and the hub has cooled down if you had to use the torch. Sand down the edges of the hub as well.
    10. Apply a light coat of anti-seize lubricant to the edge of the hub and this will help in the future when the rotor needs to be removed again for whatever reason.
    11. Replace the parts in reverse procedure and repeat the steps for the other side.
