Attach the parking brake lever to the replacement shoe by sliding the pin through the hold in the shoe and pressing the C-clip into place. Install the rear shoe, pin, spring and retainer. Make sure that the end of the pin seats itself in the groove of the retainer. Slide the adjuster bar into place and install the front shoe.

Which way does the secondary brake shoe face?

Wheel cylinder

The leading shoe (closest to the front of the vehicle) is known as the secondary shoe. The trailing shoe is known as the primary shoe. Hydraulic pressure from the master cylinder acts on the piston cup, pushing the pistons toward the shoes, forcing them against the drum.

How do you put a drum brake back on?

If you crack the brake cylinder bleed screw open (with an appropriate tube and "catch" bottle for any fluid that might leak out), squeeze the brake shoes inward with your clean hands, then close the bleed screw. The brake drum should now go back on smoothly. Bleed that brake, and move on to the other side.

What direction do brake shoes go?

Preferably a Motors Manual or factory manual. Short shoe in front . . . because it's the "self-energizing" shoe. The front shoe tries to jam itself into the brake drum - which makes it the stronger shoe braking-wise - when the brakes are applied so it's smaller to match the power of the larger secondary shoe.

How do you determine the position of the primary and secondary brake shoes for installation?

One wheel cylinder operates the brake on each wheel. Two pistons operate the shoes, one at each end of the wheel cylinder. The leading shoe (closest to the front of the vehicle) is known as the secondary shoe.

How do you install brake shoe springs?

Does the short brake shoe go to front or rear?

Short shoe in front . . . because it's the “self-energizing” shoe. The front shoe tries to jam itself into the brake drum – which makes it the stronger shoe braking-wise – when the brakes are applied so it's smaller to match the power of the larger secondary shoe.

Which side does the thicker brake shoe go on?

if the brakes are working properly the shoes should wear the same, the thicker shoe should be the front (new) more material sheds off the front because its being pulled into the drum.

Why are brake shoes different sizes?

Calipers Sizes

Front brake calipers work significantly harder than the rear, which requires them to be a different size to handle the force that is applied to them. The front and rear brake pads cannot be interchanged, as the front pads will not fit on the calipers of the rear and vice-versa.

How many brake shoes function as leading brake shoes when you are driving in reverse and break?

Structurally, it has a wheel cylinder housing a piston with which hydraulic pressure is generated to push the two shoes against the drum's inner surface. The two shoes function in a way they both become either the trailing shoe or leading shoe depending on whether the vehicle is travelling forward or backward.

What holds the primary and secondary shoes against the adjuster?

A spring connects the primary and secondary shoe to contain the adjuster. Dual Servo brakes use two primary shoes and two anchor pins. The pistons of the wheel cylinder apply both of the shoes.

Which brake shoe in a non servo drum brake assembly is energized during braking in reverse?

both non servo drum brake primary and secondary shoes are self energizing as the brakes are applied and the vehicle is moving forward.

How do automatic brake shoe adjusters work?

Each time the car stops while in reverse, the shoe is pulled tight against the drum. When the gap gets big enough, the adjusting lever rocks enough to advance the adjuster gear by one tooth. The adjuster has threads on it, like a bolt, so that it unscrews a little bit when it turns, lengthening to fill in the gap.

How do you remove springs from brake shoes?

To remove them use the round, notched part of the brake spring pliers. Place the round part on the anchor pin (the nob that the springs are hooked to) and turn it until the notch catches the spring, and then twist and pull to remove the spring. Remove the retaining rings that hold the brake shoes in place.

How long do rear brake shoes last?

Brake pads and shoes are generally thought to be good between 30,000-35,000 miles in urban use. In less demanding situations like highway driving in light traffic, brakes may last 80,000 miles or more.

What do rear brake shoes do?

Brake shoes carry the brake lining inside brake drum systems. They are a curved piece of metal, with a friction material fixed to one side. This creates friction between the lining and drum, causing the car to brake. The kinetic energy is dissipated as heat.

Do rear brakes do anything?

Rear Brake Design — Stability

Overall vehicle design determines front brakes vs rear brakes bias, but most rear brakes should never provide more than 40 percent of the stopping power at any given time. As such, they don't develop nearly as much heat as the front brakes.

How do you adjust rear brake shoes?

Do rear drum brakes self adjust?

A modicum of self-adjustment has been built into drum brake systems, but the catch is that this self-adjuster only works when the car is being driven in reverse on some vehicles and only when the parking brake is engaged in others. As the car is moving in reverse and you step on the brakes, the shoes expand.

Are linings bonded to the metal brake backing?

Brake lining material is attached to metal backing, such as a brake shoe, usually with heat-resistant rivets or joints. The lining comes into contact with the rotors creating enough friction to slow them down. The brake lining protects the rotors from coming into direct contact with the metal backing.

What is a brake spring tool?

(1) HEAVY-DUTY BRAKE SPRING TOOL. BST4480. Removes and installs larger brake return springs on brakes with or without an anchor pin.

How do you use a Eaton brake spring tool?

  • Lay spring flat on surface.
  • Pick up the spring with the pliers.
  • Be sure the spring is seated deep enough in the slot so it does not slip out.
  • Insert one end in the proper hole of the brake shoe.
  • Stretch the spring with pliers and install the other end.
  • What tools are needed to change drum brakes?

    You'll need a drum brake retainer spring tool and a pair of drum brake spring pliers. These can often be purchased as a set. You'll also need simple tools like a hammer, pliers, and other assorted hand tools to get everything apart.

    How do I know if my drum brakes need to be adjusted?

    Periodic adjustment of the drum brakes makes sure that the brakes do not drag when driving as this can rob power from the vehicle and cause the brakes to wear out much more quickly. Drum brakes usually need to be adjusted when the brake pedal has to be pressed down a lot before the brakes engage.

    Which way do you turn a drum brake adjuster?

    Turn the adjuster screw to loosen the shoes. Locate the access hole on the outside of the brake drum. Turn the brake drum so that the access hole is aligned with the drum's adjuster screw. Turn the adjuster screw counterclockwise until it comes to a halt.
