Lining thickness is dependent on a few factors. A. Is your lining bonded to the shoe or pad, or is it Rivited to the shoe or pad? B. What is the application? Lining thickness is determined ultimatley by the manufacturer. Generally speaking on Automotive and light truck applications new lining for brake shoes is between 6/32nds and 12/32nds of an inch. Add a couple 32nds if rivited. On front brake pads the lining is much thicker when new. On average a new brake pad can have lining between 10/32nds to 18/32nds. Pads are in need of replacement when bonded lining has worn to 2/32nd and rivited lining has worn to 3/32nds since the rivet head can come in contact with the disc brake rotor or drum at 1/32nds. Lining can also break free from the pad or shoe when they get that low due to rotor or drum out-of-round. This can cause lining to break free from the pad or shoe and cause dmage to the drum or rotor surface. When replacing brakes, its always good to have drums or rotors machined or replaced. For rotors, there are three specs to take into consideration. 1. Minimium machining thickness. If rotors are machined beyond their reccomended minimium machining they will warp due to heat. This warping will eventually lead to brake pedal pulsation. 2. Run-out; Run-out is measured using a dial micrometer and usually .003 to .005 of an inch is considered excessive. 3. Material Thickness Variation; or parralleism is measure with a micrometer. .0003 to .0005 ten thousandths of an inch is considered excessive. It is extremly hard to find a rotor that will pass all three of these measurements. If someone tells you the rotors do not need to be machined because they "look good", don't trust them because they don't know what they are talking about. Rotor condition can not be determined by the human eye. Drums have a maximium diameter they can not exceed, as well as an out-of-round specification as well. A good brake job will always have drums and rotors either machined or replaced. Money can be saved if they can be machined as it it cheaper to machine than replace.

SOURCE: front shoe on back passenger side is sticking.

it might be the drum that is causing the squeaks. Visually inspect the drums for excessive wear and also pits and grooves. The other option is that your return springs are REALLY bad and they might need replacing. Hope this helps.

If the light is for the parking brake check the switch that is above the parking brake pedal assembly. The switch may be bad or out of adjustment.

SOURCE: rear brakes don't work

You need to re evaluate your work for it is not assembled correctly. Some have a cable that is attached from the shoe to the self adjuster. To adjust without tearing it down again run the truck in reverse and stop it quickly. Do that 5 times and see if the emergency brakes start to work. If so the adjusters are connected correctly

What is the min thicknees on a brake shoe in inchs


brake shoe thickness is measured in millimeters or inches, with the majority measured in millimeters. The minimum thickness a brake shoe should have will vary by manufacturer. However, between 2 and 3 millimeters is generally considered the minimum allowed thickness. Brake shoe thickness can be measured by removing the wheel and brake drum, and measuring the thickness of the brake shoe through the rivet holes.

How to adjust rear brakes shoes on toyota corrolla 1999


the shoes on drum brakes should auto adjust by backing up and applying pressure to the brake pedal (you may hear a clicking noise from the springs on the adjustment stars as they turn). If this does not work, the mechanism may be broken, aligned improperly or stuck by corrosion. Most drum brake assemblies have an access hole in the drum or backing plate to make manual adjustments, comment back to me if u have these access holes and I will walk you through the procedure...(check your shoe lining thickness as you may just need new brake shoes)

How do i change the brake pads?


REMOVAL AND INSTALLATION
  1. Remove disc brake caliper from mounting bracket and support with a length of wire or remove sleeve bolt and rotate caliper up and out of the way to remove shoes. Do not allow caliper to hang by the brake line unsupported.
  2. Remove outboard shoe and lining. Use a suitable tool to disengage shoe springs from holes in caliper housing.
  3. Remove inboard shoe and lining, unsnapping shoe spring from piston.
  4. If installing new shoe and linings, bottom piston in caliper bore using large pliers. Take care not to damage piston or piston boot.
  5. Remove bushings from mounting bolt holes in bracket. To install:
  6. Install new bushings to mounting bolt holes in bracket. Lubricate bushings with silicone grease before installation.
  7. Install inboard shoe and lining by snapping shoe retainer spring into piston. Shoe retainer spring is already staked to the inboard shoe. Shoe must lay flat against piston.
  8. Install outboard shoe and lining by snapping shoe springs into holes in caliper housing. Wear sensor should be at the trailing edge of shoe during forward wheel rotation. Back of shoe must lay flat against caliper.
  9. Install caliper.
  10. Apply approximately 175 lbs. (778 N) of force 3 times to brake pedal to seat linings.

1994 corolla 1.3,rear n/side brake drum runs hot, new shoes fiitted,is it poor wheel cylinder pistons?


Check that the brake shoes are adjusted correctly and that the new shoes ar'nt to thick.It is always better to skim the drums to fit new shoes if needed.Poor wheel cylinder will cause no brakes at that wheel unless it is siezed and not releasing

Rear brake replacement


try to shorten first the adjusting bar between the shoes. this bar is used to adjust the handbrake.
it is now extended because it was used on thin brake shoe. wth the new thick brake shoe, you have to shorten this bar again.
