A Guide to Rear Brake Drums for the 1986-2002 Mercury Cougar
Understand the symptoms of failure and how to choose the right replacement brake drums for your Cougar's specific model year.
- First, confirm if your Cougar has rear drum brakes, as many 1989-1997 performance models and some 1999-2002 V6 models used rear disc brakes instead.
- Always replace brake drums, brake shoes, and the hardware kit together as a set for a complete and safe repair.
- Brake drums must be replaced in pairs (both rear wheels) to ensure balanced and safe braking.
- For most owners, a standard aftermarket drum from a brand like Centric, Bendix, or Raybestos provides an excellent combination of quality, performance, and value.
Is It Time for New Brake Drums?
Your Cougar will give you clear signs when its rear brake drums are worn out. One of the most common symptoms is a new noise, like a scraping or grinding sound when you apply the brakes. This often means the brake shoes have worn down completely and metal is now grinding against the drum's surface. You might also feel a vibration or pulsing in the brake pedal, which can happen when a drum becomes warped or "out-of-round" from heat. Another key sign is a loose or ineffective parking brake; if the drum is too worn, the shoes can't press firmly enough to hold the car securely. If you notice any of these issues, it's time for an inspection.
A Critical Note on Cougar Generations
The 1986-2002 timeframe covers three different versions of the Mercury Cougar, and their brake systems are not the same. It is essential to confirm your car's setup before buying parts.
- 1986-1988 (Fox Body): These models commonly used rear drum brakes.
- 1989-1997 (MN12 Platform): Base models were typically equipped with rear drum brakes. However, higher-performance trims like the XR7, Super Coupe, or models with a V8 often had 4-wheel disc brakes.
- 1999-2002 (FWD Platform): While all models have front disc brakes, the vast majority came from the factory with rear drum brakes. Rear disc brakes were an option on some V6 models but are less common.
Pro Tip: The easiest way to be sure is to look through the spokes of your rear wheel. If you see a solid, pot-like metal drum, this guide is for you. If you see a flat, shiny disc with a caliper clamped on it, you have disc brakes and will need rotors and pads instead.
Choosing the Right Aftermarket Brake Drum
For a daily-driven Mercury Cougar, you don't need to hunt down expensive and often-discontinued original parts. Aftermarket brands offer excellent quality that meets or exceeds factory specifications. They can be grouped into a few tiers:
- Premium Brands (Bendix, Raybestos): These are well-respected names in the brake industry, known for high-quality materials and manufacturing. They are a top choice for mechanics and owners who want maximum durability and performance.
- Standard OE-Match (Centric, Dynamic Friction): Centric is a very popular brand that offers a great balance of quality and price, making it a solid all-around choice. Dynamic Friction also provides reliable, OE-style performance for everyday driving. These brands are excellent for a standard replacement.
- Economy Brands (Pronto): Economy-tier brands provide a functional, budget-friendly option. They are suitable for older vehicles with less critical demands or if you're preparing to sell the car.
What Does a Brake Drum Replacement Cost?
The total cost will depend on the brand of parts you choose and whether you do the work yourself or hire a professional. Below are typical cost estimates for replacing a pair of rear brake drums on a Mercury Cougar.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Brake Drums (Pair) | $56.31 - $102.97 |
| Brake Shoes & Hardware Kit | $43 - $90 |
| Shop Labor | $150 - $250 |
| Total Professional Installation | $250 - $440 |
Cost estimates are for parts and labor and can vary by location and vehicle condition. It is highly recommended to replace brake shoes and hardware at the same time as the drums.
Frequently Asked Questions
Do I have to replace brake drums in pairs?
Yes, absolutely. Brake drums must always be replaced in pairs (both rear wheels at the same time). Replacing only one can cause a dangerous braking imbalance, making the car pull to one side when you stop.
What other parts should I replace with my brake drums?
For a complete and safe brake job, you should always replace the brake shoes and the brake hardware kit along with the drums. The springs in the hardware kit get weak over time, and a new kit is inexpensive. It's also critical to inspect the wheel cylinders for any signs of brake fluid leaks. A leaking cylinder will ruin your new shoes and must be replaced.
Is this a difficult DIY job?
Replacing brake drums is more complex than a simple brake pad change. It involves many small springs and clips that must be assembled correctly. Special tools like brake spring pliers are often needed. If the old drum is rusted to the hub, it can be difficult to remove. For a beginner, this can be a challenging job, and incorrect assembly can lead to brake failure.
Were there any recalls on Cougar brake drums?
No recalls were found specifically for the mechanical components of the rear drum brakes on the 1986-2002 Mercury Cougar. There was a recall for 1999 models concerning the brake *light* switch, but this did not affect the braking system's ability to stop the car.
