Overview
The Power Stop Autospecialty B670 is a rear drum brake shoe set for the 1991–2001 Jeep Cherokee (XJ) and the 1993–1994 Jeep Grand Cherokee (ZJ). It is a semi-metallic replacement shoe with a black rust-resistant coat, built to meet or exceed OEM specifications.
The shoes are post-cured for more brake power and a shorter break-in, and they are precision arc ground to match the drum. The chamfered edges keep braking quiet and free of chatter.

Cherokee rear drum upkeep
On a Cherokee XJ, rear drum shoes are often replaced together with the wheel cylinders and hold-down hardware, since these parts wear at similar rates. Clean the backing plate and check the parking brake cable for free movement before fitting. Make sure the return springs are not stretched, because weak springs can hold the shoes off the drum and reduce braking.
The semi-metallic compound on this shoe needs a proper bedding procedure. Make a few firm stops from moderate speed to transfer an even layer of friction material to the drum, then let the brakes cool before heavy use. Hot, unbedded shoes can glaze and feel weak even when the parts are new.
- Stretched or cracked return springs
- Seized parking brake cable
- Glazed or uneven lining after the first trips

Installation notes
Drum brake shoes are normally replaced as an axle set. The semi-metallic compound is post-cured for a shorter break-in, so follow the bedding procedure for new shoes after fitting. These shoes are for the rear axle only, so the front brakes use a different part.
