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.

There are a few things that make your parking brake feel loose.

The causes of a loose parking brake are not always obvious, but there are a few things that make your parking brake feel that way. The main culprit is the proportional valve, which controls how much pressure is applied to the brakes when you push down on the pedal. When this valve malfunctions, it creates excessive pressure in one area of your vehicle’s braking system and causes your car to pull towards that side while you’re driving.

Another possibility is that your parking brake shoes aren’t properly positioned or adjusted for proper contact with their corresponding drums or discs (this applies only if you have drum brakes). You may also need new springs in order to get enough tension on them so they can do their job properly—it’s important not to let them become too loose!

Also, parking brake problems can be caused by a number of issues, ranging from worn or damaged cables to bent levers. While these issues may not seem serious, they become more dangerous as the vehicle ages and parts wear out. In this article, we’ll further explain how parking brakes work and what causes your car’s parking brake to fail so that you can take steps to have it repaired before an accident occurs.

Worn or damaged parking brake cable

Usually, the parking brake cable is the first part to wear out. If it’s damaged or worn, it may not hold the vehicle in place properly when you apply the parking brake. If this happens, you’ll have to replace that portion of your car’s braking system.

If you find that your parking brake isn’t functioning properly after you’ve had a brake job done on your car, inspect its cable for any signs of damage or wear-and-tear. If it looks like there are any problems with this part, then check whether or not it’s loose or broken at both ends. This can usually be done by simply trying to tighten up each end yourself using a wrench; if they’re loose enough that they come off easily when pulled apart slightly (but not too far so that they come flying off), then chances are good that they need replacing altogether!

Bent or misaligned lever

If you think that your parking brake lever is bent or misaligned, there are a couple of things to check. First, look at the parking brake cable as it comes out of its anchor point on the rear axle. If it’s rubbing against anything at all, that could cause problems. Second, look at where your parking brake lever attaches to the cable: if it’s bent in any way, that could cause problems too.

If you’re worried about either of these issues (or just want to be extra careful), you can also buy a new cable and/or lever from [your favorite online store] and install them yourself!

Incorrect lubrication of brake caliper or shoe

You could have not properly greased the caliper or shoe. Greasing the brake pads and shoes should be done before you install them on your car. You can use a small brush to apply the grease and wipe off any excess. Using a vacuum pump can help remove any extra grease that has accumulated at the bottom of your calipers and shoes, which will allow them to move freely as they should during braking.

Binding cable

Parking brake cables can become damaged or become undone, causing the parking brake to not hold. If this happens, you may need to replace your parking brake cable.

  • The parking brake cable is a metal cable that connects the pedal mechanism in your vehicle’s footwall with the calipers on either side of your rear axle. They are usually made out of stainless steel and come in varying lengths—but if you find that your car is pulling to one side when you apply it, there may be some slack in the cable (meaning it should be replaced).

  • Another cause for this issue can be that one side of a caliper has failed, causing uneven distribution of pressure between both sides. This typically causes an audible squeal when applying or releasing your parking brake as well as uneven wear patterns on each tire’s treads. You’ll have to have both sides inspected and repaired before being able to use them again safely; otherwise they could fail completely while driving down the highway at high speeds!

Parking brake problems are important to resolve because the parking brake is the only braking system when the vehicle is parked.

The parking brake is the only braking system when the vehicle is parked. It keeps a parked car from moving and it’s important to be working properly. The parking brake should be inspected regularly and replaced if it is worn or damaged.


If you feel like your parking brake is loose after a brake job, there are a few things that could be causing it. The first thing to check is the spring tensioner and proportional valve. If either of these parts have been replaced recently or show signs of wear and tear, then they may need to be adjusted again. Another area to look at is the parking brake shoes themselves; sometimes they can become worn out enough that they don’t provide enough pressure against the drum surface when engaged.

In conclusion, parking brake problems are some of the most common issues that you can run into with your vehicle. Thankfully, these problems are easily solvable with a little bit of know-how and patience. If you’re having any trouble with your brakes, make sure to take it into a shop so they can diagnose it for you!
