Brake Master Cylinder Replacement Service

What is the Brake Master Cylinder all about?

The brake master cylinder contains brake fluid and is connected to the brakes through the brake pipes and hoses. When you step on the brake pedal, brake fluid flows from the master cylinder to the braking unit at each wheel, creating enough friction to slow down and/or stop the car. The brake master cylinder has internal and external seals that can wear out over time.

If the external seals have worn out, they will leak brake fluid, reducing the amount of fluid in the car and causing the brakes to malfunction. Worn external seals can also leak the fluid into the brake booster and destroy it. The brake booster is essential for the proper functioning of the brakes, so if brake fluid has leaked into it, replacement is required.

If the internal seals have worn out, the brake fluid will continue to circulate inside, instead of being directed to the brakes. This weakens brake performance. The brake pedal will feel soft. When you apply the brakes, the pedal will go all the way to the floor without significantly slowing down or stopping the car.

After replacing the brake master cylinder, the mechanic should flush the old brake fluid out and replace it with new brake fluid.

Master Cylinder

Keep in mind:

  • A leaking brake master cylinder can sometimes result in a broken brake booster; in this case, both elements will need to be replaced.
  • Brake systems are extremely sensitive to debris, so they need to be cleaned thoroughly before and during the replacement of a master cylinder.
  • The air will need to be bled out of the system before the new master cylinder is installed.

How it's done:

  • Inspect brake master cylinder for leaks.
  • Inspect brake booster.
  • Remove and replace the brake master cylinder if faulty.
  • Change the brake fluid.
  • Bleed entire brake system of air.
  • Clean brake fluids from all the wheels.
  • Perform brake safety inspection.

Our recommendation:

Your mechanic should check the amount of brake fluid every time the car is serviced. If you feel a change in the way your brake pedal feels (a softer pedal), you should have a mechanic inspect the master cylinder and brake hoses. In most cars, the brake warning light should come on when the amount of brake fluid is lower than the manufacturer’s recommended amount.

What common symptoms indicate you may need to replace the Brake Master Cylinder?

  • Brake warning light is on.
  • Brake fluid leak (clear fluid on the ground or under the brake pedal inside the car.)
  • Soft brake pedal (pedal goes all the way to the floor when pushed).

How important is this service?

All services associated with proper function of your brakes are important. In addition to safety issues, ignoring small repairs can quickly lead to more serious (and more expensive) problems.

People say the nicest things



Tom went above and beyond to make me as satisfied as I could be. His communication was excellent. Friendly and professional and best if all, my car is running great and he did it without unnecessary repairs. I would and will highly recommend Tom and Your Mechanic to everyone. Thanks, Rob Miller.



I have to be honest, this was the first time that, I have EVER felt 'at-ease' around an auto mechanic. Jonas was thorough and straight forward with me about the issues; gave me a quote directly after doing the diagnostics on the car and, as it turned out, it cost me less than the original estimate. When does that ever happen with auto repairs ?? He was friendly, informative and knowledgeable. You folks made the whole experience convenient and painless. I'm "sold" on the "Your Mechanic" concept. I'll probably never take my car again to a traditional mechanic !! Jonas was a pleasure to deal with !



Very impressed with the quality of work. Ned was on time and on budget. There were no surprise extra costs. Ned even helped me out with my other car, even though I didn't have an appointment for the other car. He took care of all of my car problems and he even found me a coupon for an oil change. I will be using this service again.
