Which brake shoe goes to the front on drum brakes?
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.

The rear shoe is pushed harder into the drum as the anchor pin prevents from rotating. Thus the rear shoe does most of the braking work.
How do you disassemble drum brakes?

- Use a screwdriver to remove the screws securing the brake drum to the wheel.
- Draw the brake drum forcefully towards you.
- Use a screwdriver and rubber mallet or a brake drum puller to take the drum off of the wheel if you are unable to remove the drum by unscrewing it and pulling it.
Do drum brakes have calipers?
Instead of housing the major components within a metal drum, disc brakes use a slim rotor and small caliper to halt wheel movement. Within the caliper are two brake pads, one on each side of the rotor, that clamp together when the brake pedal is pressed.
How do you remove a drum brake assembly?
What is the difference between the leading and trailing shoes in a drum brake?
In drum braking systems, the leading shoe is one that rotates in the direction of the drum. The trailing shoe is on the other side of the assembly, and pulls away from the rotating surface. Leading-trailing shoe braking systems are just as capable of stopping reverse motion as they are at stopping forward.
