SOURCE: rear brake replacement

ok listen to me closely! There is an adjuster on ford aspires i cant remember if its the top or bottom but you will see the part im talking about. This piece sits directly between the brake shoes. This has been adjusted out and made longer which is normal with worn shoes! You need to twist the adjuster all the way in with new brake shoes. This part your gonna be looking for has a little round wheel on it with tiny little jaggers all the way around that wheel. It is made this way so that once it gets where its suppose to be it cant back off. Self adjusters is what you need to be looking for so if you cant find on your car google it "self adjusters for rear brake shoes" that will fix you right up, just remember run that little feller all the way in. Then that brake drum will slide right on there for ya

Have a look at bleeding procedure OF BRAKE SYSTEM. i think it helps.
There are no special bleeding procedures for the ABS SYSTEM. For bleeding, please use the standard rules as described for the conventional brake system as follows: 1. Remove the reservoir cap and fill the brake reservoir with brake fluid.5eb649a.jpg
Do not allow brake fluid remain on a painted surface. Wash it off immediately. When bleeding by pressurized fluid, do not depress the brake pedal. 2. Connect the vinyl tube to the wheel cylinder bleeder plug and insert the other end of tube in a half-full container of brake fluid.
1a15ab3.jpg 3. Slowly pump the brake pedal several times. 4. While depressing the brake pedal fully, loosen the bleeder plug until fluid starts to run out. Then, close the bleeder screw. 5. Repeat steps 3 and 4 until there are no more bubbles in the fluid. 6. Tighten the bleeder plug screw. 7. Repeat the above procedure for each wheel in the sequence shown in the illustration.

IT IS POSSIBLE THE WHEEL CYLINDERS are wrong and need too much fluid to push brakes out. or rear shoes are not adjusted correct. this could be from drums too big(unlikely since new) shoes are not fitting to drum correct.You can take shoes off and set them in drum the whole shoe should contact drum sometimes just the ends contact. If this is case sand off ends of lining to make it fit .
If wheel cylinders are bad they would leak. might try a different brand of cylinders.

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.

I have a 23 t bucket and i cant get a brake pedal.when i bought it had very little brake so i replaced rear shoes and cylinders,front pads and calipers,all new lines and the master cylinder


Once you have bled the air from the brake lines,clamp off the front brake hoses carefully.Does the pedal feel better now?
Then the pad /caliper fit is allowing too much play.Is the pedal the same?Then clamp the rear hose and try the pedal.Is it fine with the rear hose clamped?If so we now know the problem is at the rear brakes.One common low pedal rear brake cause is brake shoes that do not fit the drums.Remove the drums and look at the shoes,are they showing contact wear fully or just in the middle of the shoe?Remove a shoe and place it in the drum.Can you rock the shoe against the drum surface?Once drums have been resurfaced,the shoes will not fit fully against the drum allowing the shoe the flex when applying pressure to it and this can easily create a low soft brake pedal. Of course rear brake adjustment must be correct once brake shoe contact is correct.To correct brake shoe contact,have your shoes re arc-ed to fit resurfaced drums or install new drums.Don't overlook brake master cyl /brake pedal push rod adjustment too.

I put new brakes in my saturn. i put new front calipers,rotors and pads and power bleed front only. i also put new brake pads in rear but did not replace drums.after all that i can't get a hard brake...


try adjusting the rear brake shoes but.....spin the rear wheels first is u get the feeling of the shoes grabbing then releasing ( the tire gets loose then tight as u rotate it) u will need to have the drums cut on a brake lathe or replaced...when u have this done , then adjust the rear shoes until u get a slight drag on the rear wheels..go pump the brake pedal to seat the shoes if the wheel spins free adjust the shoes more an repeat until they have a slight drag after pumping the brake pedal

I need to adjust my rear brakes. 95 camaro


ADJUSTMENT
  1. Raise and safely support the vehicle.
  2. Remove the tire and wheel assemblies.
  3. Remove the brake drums.
  4. Set drum-to-brake shoe clearance gauge J 21177-A, or equivalent, so that is contacts the inside diameter of the brake drum. Fig. 1: Set the brake clearance gauge to the inside diameter of the brake drum . . . 88149g24.gif

  5. Position the gauge over the brake shoes. Fig. 2: . . . then place the gauge over the outside of the brake shoes 88149g25.gif

  6. Turn the brake adjuster until the brake shoes contact the clearance gauge. The outside diameter of the primary shoe and the secondary shoe will be about 0.050 in. (0.127mm) less than the inside diameter of the drum on each wheel.
  7. After the adjustment is complete, install the brake drum.
  8. Install the tire and wheel assemblies.
  9. Carefully lower the vehicle, then test drive the vehicle, making several stops applying a firm force to the brake pedal. Repeat this until good pedal reserve is built up.

When I apply the brakes on my '02Dakota only the forward brake shoe moves against the drum. Have replaced wheel cylinder but makes no difference. Both shoes move when I loosen adjuster cable. Have this...


you mean parking brake cable? loosen parking brake cables put drums on , and adjust shoes till they lightly drag, now apply brakes a few times and check the adjustment again, if all ok, now adjust park brake cables, you want to adjust so park pedal goes 5-8 clicks till the wheels are "locked up" and the wheels spin free with the park brake off

Brake pedal vibrates while braking and doesent stop right away


There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

The rear drum brakes:
  • Have internal shoes that expand against the brake drum (1126).
  • Are a single-anchor type.
  • Are actuated by one rear wheel cylinder (2262).
  • Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
  • Adjust rear brake shoes and linings (2200) automatically.
  • Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.
When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .

Vibration in brake pedal


The rear shoes and drum are not in even contact when braking, thus resulting into entire vehicle vibration. The most likely cause of misalignment is a warped rear drums. However, it is possible that the drums are ok, but rather the rear wheel bearings are worn or loose, this would likely cause misalignment between shoes and drums
