Detailed Description

DuraGo BD8999-01 is a rear brake drum engineered from DuraGo’s long-term brake component experience and manufactured in an ISO certified factory. The drum uses a composite construction with a cast iron / steel top, a 13.46 in. outside diameter, a 3.1 in. center hole diameter, and a 139.7 mm bolt circle diameter to match the specified rear drum brake applications. The coated hat and edge help resist corrosion in exposed conditions, making this a practical replacement for drivers looking for a rear brake drum for 1995-2000 Chevrolet Tahoe, 1995-2000 GMC Yukon, and 1999-2000 Cadillac Escalade models. This part number, BD8999-01, is also cross-referenced to 15016408 and 15622364 for the same application.

What It Helps Address

• Rear brake drum wear or scoring
• Corrosion on the drum exterior, hat, or edge
• Brake pulsation caused by an out-of-spec drum surface
• Reduced braking consistency from an aged rear drum assembly
• Fitment issues when replacing a 6-lug 11-inch rear drum on select GM vehicles

Installation Notes and Tips

Verify drum diameter, bolt pattern, and brake surface width before installation. This rear drum is listed for rear position use only and is specified for select 6-lug applications with 11-inch rear drum requirements. Confirm the vehicle’s year, make, model, and rear brake configuration against the fitment data before ordering. For best results, inspect rear brake shoes and related hardware for wear and replace any out-of-spec components during service.

Quality Assurance

DuraGo manufactures this Titanium Series brake drum in an ISO certified facility to support fit, form, and function requirements. The corrosion-resistant coating and engineered dimensions are intended to provide consistent replacement performance for the listed Chevrolet Tahoe, GMC Yukon, and Cadillac Escalade rear brake applications.
