Why Master Cylinder Block Off Plugs are Essential
I remember the first time I heard about master cylinder block off plugs. I was working on my car and my mechanic friend told me that I needed to install them before bleeding the brakes. At first, I was confused and didn’t understand why they were necessary. But after some research and personal experience, I now know how crucial they are for the proper functioning of a vehicle’s braking system.

This can lead to decreased braking performance and potential damage to other components of the braking system. By blocking off the master cylinder with these plugs, you can ensure that your brake fluid
