Parking brake repair is something that must be carried out as part of any routine maintenance on a braking system. The parking brake is actually a very vital aspect to the safety of the car. The repair of a parking brake is very easy for anyone do it.
Make Minor Adjustments
The first thing you will need to do is make some small adjustments. With time, parking brake systems wears. A parking brake system is made with a bunch of pulleys and cables. These cables will work and stretch over time. First, check your service manual to make sure you are handling the adjustments correctly. When you make the adjustments, you will tighten the cable, or remove the additional ‘slack’.
Most times you will find that a parking brake will stick. It often times does not release as easily as it should and other times it wont pull or push back to its off position. It makes life difficult and gets the driver frustrated. Generally, when a parking brake starts to stick, you should take out a bottle of lubricant and do the greasing in between the sliding mechanisms. In addition, apply additional lubricant to the actuator levers. The levers are found on the rear brake calipers. Even after you have applied the lubricant, you may still find that the parking brake is still sticking. In this situation, you will be required to remove the rear brakes and review the entire parking brake mechanism to show the sticking problem. This is a little more time consuming but certainly worth it.
Change Broken Cable
Changing a broken cable is a fairly easy and straight forward process for anyone that is slightly skilled.
Put the car up in the air with the use of jacks and a jack stand. Pull a part the braking system to show the end of the brake cable. Remove all the mounting components so that you can get to the individual cable. Then, lightly free the cable from the calliper. Take out the existing cable from all the attachment points on the interior of the car. This is not a difficult process but can require a little patience and moving things around from side to side.
Once you have the direction of the cable fully traced, disassemble any trim required. This will give you an ability to gain access to the bottom of the parking brake handle. Remove the interior parts of the cable. draw the cable out from under mat of the car.
Following the same process, you can add the new cable. Trace your path in reverse and add the components back as needed.
Use of a Diagnostic Tool
Some modern cars feature electric parking brakes. These brakes work in the same manner as cable-operated systems, but use electric motors instead of physical effort to apply the brake. Electric parking brakes may need the use of a factory scan tool to place them into a service mode before repairs are carried out. Unskilled mechanics may find this frustrating, as performing a rear brake job is impossible without first electronically releasing the brakes.
A properly maintained parking brake will not only help your car pass required safety inspections
