Multipl

If you are needing to put in extra effort with your right foot to get your BMW to stop and all other components are in good shape, your brake booster might be failing or has already failed. The brake booster uses vacuum created by the engine to multiply the force that your foot applies to the master cylinder. This is what allows your car to come to a complete stop without a ton of physical effort from you. The seals inside the vacuum booster can go bad over time causing issues with braking force.

Note: Before writing off you current vacuum booster, inspect all air lines attached to the brake booster as tears/holes in these vacuum lines can cause symptoms similar to a brake booster failure.
