Causes of parking brake loose after brake job; If your vehicle’s brake pedal feels like it isn’t engaging like it used to, there are a few common issues you should look into. The first thing to check for is any fluid leaks near the master cylinder or wheel cylinders. If you have a leak in either location, it could be an indicator of worn parts that need repair or replacement. Another possible cause is if the parking brake shoes have become worn out over time and need replacing. Additionally, if your proportional valve is sticking open or closed then this can also lead to less braking power when trying to stop your vehicle in an emergency situation such as heavy traffic conditions where another driver may not be paying attention as much as they should be while driving behind you.

Proportional Valve

The proportional valve is a device that regulates the hydraulic pressure on your brakes. It is responsible for maintaining an even flow of fluid to both front and rear brakes. If it is faulty or if there is something wrong with it, you may feel that your brakes are loose. A professional mechanic can replace this part if needed.

Parking Brake Shoes

If your parking brake shoes are worn out, they won’t hold the car in place when you apply the parking brake. You’ll need to replace them before you can use your vehicle as a daily driver again.

The good news is that replacing the parking brake shoes is an easy project for most people—unless you have no idea what it means to “lift up on the release lever” or what “pulls back on the handle.” If this sounds like your situation, then please hire a professional mechanic like me to do this work for you (and I’m totally not biased).

Spring Tensioner

The spring tensioner is a piece of metal that is attached to the parking brake pedal. The spring tensioner is responsible for applying pressure to the parking brake shoes via a cable.

If there are any issues with your spring tensioner, it can lead to your brakes feeling loose after a brake job. If this happens, you may need to have your spring tensioner replaced by an auto repair professional.
