Pontiac Montana Brake Drum Sets

Pontiac Montana Brake drum sets

Brake drum sets for your Pontiac Montana start at $102.95, with 1 options in stock from Detroit Axle. Brake drums work with brake shoes to slow the vehicle by creating friction inside a rotating drum. When drums wear, crack, or go out-of-round, stopping distances increase and brake fade becomes a real safety risk.

Signs your Pontiac Montana needs new brake drums

  • A pulsating or grabbing sensation in the brake pedal when slowing to a stop
  • Rhythmic thumping or scraping noise from the rear wheels during braking
  • Vehicle pulls noticeably to one side when the brakes are applied
  • Visible deep grooves, score marks, or heat cracks on the drum's inner surface
  • Brake pedal travels unusually far toward the floor before the vehicle slows
  • Burning smell or excessive heat radiating from the rear wheel area after normal driving

Which brake drum set should you buy for your Pontiac Montana?

The main decision comes down to drum material, finish, and whether the drums meet or exceed OE wall-thickness specifications. Drums that are too thin after machining can crack or warp under heat, so always check that the replacement matches or improves on the original minimum thickness rating. Buying a matched set ensures even braking performance side to side.

Replacing brake drums on a Pontiac Montana

Moderate⏱ 1.5–3 hoursFloor jack and jack standsLug wrench or impact gunBrake spoon or adjuster toolNeedle-nose pliers and brake spring toolWire brush and brake parts cleaner

Loosen the wheel, raise and secure the Pontiac Montana, then remove the wheel and slide the drum off — if it is stuck, back off the self-adjuster through the access slot in the backing plate before forcing it. Inspect the wheel cylinder, hardware, and shoes before fitting the new drum, and clean all mating surfaces with brake parts cleaner. After reassembly, adjust shoe clearance so the drum spins with light drag, then pump the brake pedal to a firm feel before moving the vehicle.

Frequently asked questions

How much does it cost to replace brake drums on a Pontiac Montana?
Parts alone start at $102.95 for a set on your Pontiac Montana. Add shop labor — typically one to two hours per axle — and total costs rise depending on your area and whether brake shoes, hardware, or wheel cylinders also need replacement. Replacing drums and shoes together at the same time saves labor cost.
How long do brake drums last on a Pontiac Montana?
Brake drums on a Pontiac Montana typically last anywhere from 150,000 to 200,000 miles under normal driving conditions, but towing heavy loads, frequent mountain driving, or neglected brake shoe replacement can cut that lifespan significantly. Inspect drum thickness and surface condition at every brake service interval.
Can I replace just one brake drum on my Pontiac Montana?
No — always replace brake drums in axle pairs on your Pontiac Montana. Installing one new drum alongside a worn drum creates uneven friction and braking force, which causes the vehicle to pull to one side under braking. Matching both sides maintains stable, straight stopping and is the industry-standard practice.
Should I replace brake shoes at the same time as the drums on my Pontiac Montana?
Yes, in most cases. If the drums on your Pontiac Montana have worn grooves or an uneven friction surface, new shoes will wear unevenly against that surface and may not bed in correctly. Replacing both together ensures proper contact, consistent friction, and prevents a repeat job in a short period of time.
Can brake drums be resurfaced instead of replaced on a Pontiac Montana?
Drums can be turned on a brake lathe if enough material remains above the minimum discard thickness stamped on the drum. If a drum on your Pontiac Montana is at or below that spec, it must be replaced — a drum that is too thin overheats quickly, warps, and poses a serious safety hazard.
Are brake drums hard to replace on a Pontiac Montana?
Brake drum replacement on a Pontiac Montana is a moderate DIY job. The drum typically slides off once the wheel is removed, provided the shoes are backed off with the adjuster. The more time-consuming part is adjusting the new shoes to the correct clearance and properly lubricating all contact and hardware points.
