How to Troubleshoot if Your Emergency Brake is Not Working After a Brake Job

AvatarByCarl Frisch

Emergency brake not working after brake job is a common issue that occurs when brakes are replaced. This can happen due to a variety of reasons, such as incorrect installation, not properly bleeding the brakes, or using the wrong parts. In some cases, the emergency brake mechanism may have been damaged during the brake job. If this is the case, it will need to be replaced. Additionally, sometimes debris or dirt can get into the system and cause it to malfunction. If this is the case, it will need to be thoroughly cleaned out before attempting to use the emergency brake again.

Weak or Loose Cables

When it comes to emergency brakes not working after a brake job, one of the most common causes is weak or loose cables. When performing a brake job, it is important to check the cables for any signs of wear and tear. If there are weak or loose cables present, they will need to be replaced in order for the emergency brake to function properly. It is also important to make sure that the cables are not crimped or pinched in any way as this can also lead to issues with the emergency brake not functioning properly.

Faulty Components

Another potential cause of an emergency brake not working after a brake job is faulty components. This includes any parts that may have been damaged during installation or were simply faulty in the first place. Common components that can cause issues include calipers, rotors, drums, and pads. If any of these components are not functioning correctly, they may prevent the emergency brake from engaging properly and lead to an overall decrease in braking performance.

Worn Out Shoes or Pads

Worn out shoes or pads can also be a cause of an emergency brake not working after a brake job. Shoes and pads tend to wear down over time due to regular use and heat build-up within the braking system. Worn out shoes and pads will need to be replaced in order for the brakes to work correctly again. It is important to ensure that the correct size shoes and pads are being used as using incorrect sizes can lead to further issues with braking performance.

Issues with Caliper Bolts

Finally, another less common cause of an emergency brake not working after a brake job is issues with caliper bolts. Caliper bolts can become corroded over time due to exposure to moisture and other elements which can cause them to seize up or become loose if they are not checked regularly. If there are any issues with these bolts then they should be replaced as soon as possible in order for the brakes to function correctly again.

Checking the Emergency Brake Cable System

When diagnosing an emergency brake not working after a brake job, it is important to first check the emergency brake cable system. This system consists of cables that connect the emergency brake lever to the brakes on each wheel. The cables should be inspected for wear and tear, as well as for any loose connections or corrosion. If any of these issues are found, they should be addressed before further testing is conducted.

Testing the Braking System Components

After ensuring that the cable system is in good condition, it is time to test the other components of the braking system. The shoes and drums should be inspected for wear and damage, as these are key components in proper braking performance. Additionally, it is important to verify that all rotors and calipers have been properly installed on each wheel.

If any of these components are found to be worn or improperly installed, they must be replaced in order to ensure safe braking performance. Once all components have been inspected and replaced as needed, it is time to test the emergency brake by gently depressing the lever while monitoring the brakes’ response. If there are no issues with the response, then your emergency brake should now be working correctly after a brake job.
