Detailed Description

DuraGo BD920134 is a rear brake drum for Mitsubishi Lancer models that require a 5-lug, 114.3 mm bolt circle drum with a 203 mm nominal diameter. The cast iron, full cast construction supports consistent braking surface characteristics, while the dimensional specs help confirm proper rotor-to-hub and shoe-to-drum fitment during brake service. This part number, BD920134, is part of DuraGo’s brake drum and rotor program, which is manufactured in ISO certified factories to meet fit, form, and function requirements.

Compatible With 2008-2009 Mitsubishi Lancer, rear and 2011-2016 Mitsubishi Lancer, rear. This part cross-references Four Seasons 35123 for the same application. BD920134 is a practical choice when replacing a worn rear drum on a Mitsubishi Lancer and when matching OE-style dimensions matters for brake shoe contact and pedal feel.

What It Helps Address

• Rear brake pulsation caused by drum wear or out-of-round condition
• Reduced braking consistency from an over-machined or worn drum surface
• Brake shoe contact issues related to incorrect drum diameter
• Noise or vibration from a damaged rear drum
• Service replacement for a Mitsubishi Lancer rear brake drum

Installation Notes and Tips

Verify the drum diameter, bolt circle, center hole, and brake surface width against the removed part before installation. Measure the existing drum against the maximum brake diameter discard specification of 205 mm (8.07 in.) and replace if the drum is beyond service limits. Clean the hub and inspect brake shoes, hardware, and wheel cylinders during service to confirm proper rear brake operation on the Mitsubishi Lancer.
