Description

Overview

The Crown Automotive J8120393 is a drum brake shoe and lining set for 10 inch brakes, usable on the driver or passenger side at the front or rear. It fits the 1966–1971 Jeep CJ5, CJ6, Commando and Jeepster (Commando).

The lining comes on the shoe, so the part is a direct-fit replacement for a worn shoe at any wheel of a listed vehicle.

Key features

  • Brake shoe and lining
  • For 10 inch brakes
  • Driver or passenger side, front or rear
  • Direct-fit replacement design

Drum shoe replacement

A drum brake shoe carries the lining that presses against the drum to slow the wheel. As the lining wears, the shoe gap grows and the brake pedal can feel low until the brakes are adjusted. Before fitting new shoes, inspect the drum for scoring, cracks and out-of-round wear, since a worn drum will wear a new lining quickly and cause pulling or noise.

Shoes are usually replaced as a set on each axle, so the lining wears evenly. Check the wheel cylinder for leaks, the springs and hold-downs for wear, and the adjuster for smooth movement. Clean the backing plate and lubricate the shoe contact points lightly, keeping grease off the lining. After fitting, adjust the shoes so the lining contacts the drum evenly.

  • Inspect the drum for scoring or cracks
  • Check the wheel cylinder for leaks
  • Adjust shoes after installation

Questions & Answers

What brake size is the Crown J8120393 for?

It is for 10 inch drum brakes, and it fits the driver or passenger side at the front or rear.

Does the J8120393 fit a 1968 CJ5?

Yes. It fits the CJ5 and CJ6 for 1966–1971, along with the Commando and Jeepster, so a 1968 CJ5 falls in that range. Confirm your year, model and trim before ordering.

Does the J8120393 fit a CJ7?

No. The CJ7 is not in Crown's list for this part, which covers the CJ5, CJ6, Commando and Jeepster for 1966–1971 only.

How do I know the brake shoes need replacing?

Replace them when the lining wears close to the rivets or the brakes pull, squeal or feel weak. A low pedal that needs frequent adjustment can also point to worn shoes.

Should the wheel cylinder be checked with new shoes?

Yes. Look for fluid leaks at the cylinder boots and check the pistons for smooth movement. A leaking cylinder can soak new lining and make the brakes fail quickly.
