SOURCE: Rear Axle Bearing

i know for a fact that the bearing comes with the hub., and if the old bearing is badly damage you may need to heat it to remove it from the axel...so this may be a rather big job if your not equipt
with torch or other ...

SOURCE: Brake Problem

hi im dave
hope i can help
when you had the rear pads applied and the discs turned was there noticeable damage to the disc surface it sounds like your e brake cable is not adjusted properly or perhaps the braided wires inside the insulation are seperating along your brake cable causing the rear brakes to not be adjsting themselves properly. Every time the parking brake is applied the rear brakes are self adjusted if they arent being applied due to slack in or a broken cable you will not adjust your rear brakes. This would accont for the flutter in the brake pedal as hydraulic fluid is still circulating to compress the pads against the rotor but the pads arent reaching the rotor.

most likely a brake line causing problem. it is either the rubber hose or caliper sticking. the rubber hose will collapse and cause pressure to stay on the caliper

SOURCE: Adjusting Padking Brake with 4 wheel disc brakes.

Hope this helps. This is out of the factory manual. Let me know if this works for you.
PARKING BRAKE NOTE: Tensioner adjustment is only necessary when the tensioner, or a cable has been replaced or disconnected for service. When adjustment is necessary, perform adjustment only as described in the following procedure. This is necessary to avoid faulty park brake operation.

  1. Raise vehicle.
  2. Fully back off cable tensioner adjusting nut at equalizer to create slack in cables.
  3. Remove rear wheel/tire assemblies. Remove brake calipers and rotors.
  4. Verify park brakes are in good condition and operating properly.
  5. Verify park brake cables operate freely and are not binding, or seized.
  6. Check park brake shoe adjustment.
  7. Reinstall rotors and make sure rotors turn freely.
  8. Reinstall brake calipers. Tighten guide pin bolts to 41 n·m (30 ft.lbs.)
  9. Reinstall wheel/tire assemblies after brake shoe adjustment is complete.
  10. Lower vehicle enough for access to park brake foot pedal. Fully apply park brakes
NOTE: Leave park brakes applied until adjustment is complete.
  1. Raise vehicle again.
  2. Mark tensioner rod 6.35 mm (1/4 in.) from edge of tensioner bracket Adjustment Mark On Cable Tensioner Rod
  3. Tighten adjusting nut at equalizer until mark on tensioner rod moves into alignment with tensioner bracket
CAUTION: Do not loosen, or tighten the tensioner adjusting nut for any reason after completing adjustment.
  1. Lower vehicle until rear wheels are 15-20 cm (6-8 in.) off shop floor.
  2. Release park brake foot pedal and verify that rear wheels rotate freely without drag. Verify pedal returns to fully released position.
  3. Lower the vehicle

Brakes juddering, not rear drums front discs appear good.


no
the problem most likely is warped discs
this makes the pistons move in and out and pulses under the foot
take the discs to an accredited brake shop and have them checked and machined
ABS systems do not work until a skid situation is reached, then the abs pump cuts in and maintains brake line pressure according to brake pedal pressure
oil on brake lining and disc pads will also give problems so have the shop do a proper inspection

Repair shop said need new pad rotor caliber. Leaky master cylinder. MC was replaced by same shop 12mos ago. I believe MC cause brake problem.


always get a second opinion if you've never used that mechanic. If you dont know what your looking at then go to another shop for another opinion,but i wouldnt think a leaky MC would mess up the whole brake system, ive never had that problem.

Why does the pedal vibrate while vehicle is moving?


brake pedal I take it
this from warped disc rotors for the brakes
the warp makes the caliper pistons move in and out and this comes back to the foot pedal
the problem is bad original discs fitted from the factory , discs been machined past acceptable limits
the fix is new after market , quality discs with new disc pads

1995 suburban the whole truck shakes when i apply the brakes and the pedal seems to pulse as it slows to a stop. I have changed the front pads calipers and rotors. no change ?


Now, did the mechanic even suggested anything about MACHiNiNG ur ROTOR brake disc before putting those brake pads? U got UNEVEN brake disc and needs MACHiNiNG to equally level the pads grip to the rotor! Do it i'm very sure of it! Taaah!

REAR BREAKS VIBRATE WHEN APPLYING BREAKS.


If it has drum brakes get the drums machined or if it has discs get the discs machined to stop the vibration as with age and heat and water splashes over time the discs and or drums go out of round causing the pads(discs) shoes (drum brakes)to cause a vibration when they are applied,

Installing front brake pads


    • Some of the fluid from the master cylinder
    • Wheels
    • 2 caliper guide pin bolts
    • Caliper assembly by swinging the top part of the caliper away from the brake rotor edge, then lift the caliper assembly up
    • Outboard brake pad by prying the brake pad retaining clip over raised area on the caliper. Then slide the pad down and off the caliper.
  1. Before removing the inboard brake pad, use a large C-clamp to press the piston back into the caliper. This will prevent possible damage to the caliper piston. It is good practice to remove some (1/3–1/2) of the brake fluid from the reservoir. This is because as the caliper piston is pushed back into the caliper, brake fluid will be pushed back through the lines, back into the master cylinder and fluid reservoir, possibly causing the reservoir to overflow.
    • Inboard brake pad by pulling away from piston until the retainer clip is free from the cavity in the piston. 0900c152802197b8.jpgRemoval and installation of the disc brake pads
To install:
  1. Lubricate both the caliper mating surface and the machined abutment surfaces with multi-purpose lubricant.
  2. Before brake pad installation, be sure to lightly coat the outer backing plate surface of the new brake pads with a disc brake pad anti-squeal lubricant, usually a gel-like material that deadens any high-frequency vibration that can be the source of disc brake squeal.
  3. Install or connect the following:
    • Brake pads into the caliper assembly making sure both pads are seated securely onto the caliper
    • Caliper assembly back into position over the brake rotor
    • Caliper guide pin bolts and torque to 17 ft. lbs. (23 Nm)
    • Wheels and lug nuts. Torque the lug nuts, in a star pattern sequence, to 100 ft. lbs. (135 Nm).
  4. Top off the master cylinder to the appropriate level, using DOT 3 type brake fluid only.
  5. Before moving the vehicle, pump the brakes until a firm pedal is obtained. Road test the vehicle to make sure the brake operation is normal.
