Q: Master cylinder and brake booster leaking

asked by on

The brake booster and master cylinder in my truck are leaking.

Worn master cylinder seals can cause brake fluid to leak into the brake booster, damaging it. I’m guessing this is what happened to your truck. Replacing both the master cylinder and brake booster is the only way to solve this problem. A trained professional, such as one from YourMechanic, can do this for you.
