Brake Boosters

At B & R Brakes – Castle Hill, we specialize in restoring brake boosters, even the most challenging units that were never designed to be serviced. From common booster types to sealed units that come crimped together, we have the tools, expertise, and experience to bring your booster back to life.

Brake Booster Restoration Process

We can restore most brake boosters, including some that were once thought to be unserviceable. Here’s how we handle your restoration:

1. We carefully dismantle the booster to assess its condition and identify any faults.
2. Order the required parts and carefully reassemble
3. After restoration, each booster is rigorously tested on a purpose-built test rig for output, vacuum, and hydraulic performance.
4. Once the booster passes all our bench tests, we powder coat the cans to enhance its longevity and durability.
5. Your restored booster is ready for collection or shipping back to you.

Common Faults We Address

Brake boosters can suffer from several issues which we can repair for you, including:

• Ruptured Diaphragms: The rubber diaphragm can wear or rupture, causing a loss of braking assistance.
• Seal Failure (Hydrovacs): This can lead to internal fluid leaks, compromising the booster’s function.
• Broken or cracked valve bodies

At B & R Brakes – Castle Hill, we have the skills and equipment to restore your brake booster to peak performance. Whether you need to repair a Hydrovac or Mastervac, we ensure that your brake system operates at its best, giving you confidence in your vehicle’s safety and reliability.
