How to replace the brake master cylinder?

A brake master cylinder is one of the most crucial components of a vehicle’s brake system. But, how do you know you need a new master cylinder?

 Step 1: Before you start unscrewing the cylinder, try to remove as much fluid as possible from the main brake cylinder. To extract brake fluid from the master cylinder, use Turkey Baster.

Step 2: Now start removing various components that lead directly to the master cylinder. Carefully remove all the tubes and components like brake booster vacuum hose so that you can easily reach the master cylinder.

Step 3: Now, search where a fluid level sensor is. It is generally located on the plastic reservoir. Locate and unplug it.

Step 4: With the help of line wrench, crack open the brake lines, with the brake master cylinder still secured to the brake booster. There are approximately 4 brake lines connected to the master cylinder. Tighten them once again to avoid any leakage or spillage.

Step 5: Now unscrew each bolt that secures the master cylinder to the brake booster. Your new master cylinder will already have a reservoir, so you need to remove the old one.  But, before you pull out the old master cylinder, make sure you have prepped up your new cylinder.

Step 6: Finally using the vice, secure the new master cylinder in place. Once the new master cylinder is installed, add new brake fluid and bleed the brakes.
