PowerStop B778 Drum Brake Shoe - Rear

Rear Brake Shoes for Mitsubishi Lancer

PowerStop B778 rear Autospecialty brake shoes are built for drivers who need a direct-fit drum brake shoe with consistent pedal feel and reliable parking brake performance. This set is compatible with 2002-2007 Mitsubishi Lancer rear applications and uses a semi-metallic friction formula for strong stopping response.

The PowerStop Autospecialty brake shoe line focuses on OE-style fitment and practical noise control. For the Mitsubishi Lancer rear brake shoe application, the shoes are post cured for shorter break-in time, precision cam ground for drum fitment, and chamfered to help reduce chatter.

Product Details

PowerStop B778 is a rear drum brake shoe set engineered for the 2002-2007 Mitsubishi Lancer. The semi-metallic lining is post cured to support quicker bedding-in, while the bonded construction and cam-ground profile help maintain consistent contact inside the drum. This part cross-references Raybestos Brakes 778PG for the same application.

As part of the PowerStop Autospecialty brake shoe line, B778 is focused on OE-standard fit and material quality. The shoes are made from new steel with a rust-resistant coating, and the friction material is asbestos-free and copper-free for a cleaner material composition.

Common Brake Issues It Can Address

• Reduced rear braking performance on a drum brake setup
• Poor parking brake engagement on a Mitsubishi Lancer rear axle
• Brake shoe noise or chatter from worn or uneven linings
• Longer-than-normal break-in after brake service
• Corrosion on older rear brake shoe backing plates

Installation Notes

Install B778 on the rear drum brake assembly only for the listed Mitsubishi Lancer years. Inspect the drums, wheel cylinders, return springs, adjusters, and parking brake hardware before assembly, and replace worn components as needed. Proper adjustment and a careful bedding-in procedure help the semi-metallic lining seat correctly against the drum.

Quality Assurance

PowerStop builds its Autospecialty brake shoe line to meet strict OEM standards for fit and material consistency. The B778 uses precision-ground shoes, chamfered edges, and rust-resistant steel construction to support dependable service in rear drum brake applications.
