Hand brake won’t engage Inspection
Hand brake won’t engage Inspection Service
Engaging your hand brake ensures that your car doesn’t roll when you park on a hill. This is important in a wide variety of situations, whether you’re parking at home and your driveway is angled, or you’re backing down a boat ramp to unload in the lake. If your hand brake won’t engage, then you’re relying solely on the transmission’s park setting to hold the vehicle in place, which is never a good thing. It could slip, and it could also cause damage to the transmission.
How this system works:
Most hand brakes (sometimes called parking or emergency brakes) are relatively simple affairs – really nothing more than a cable that attaches to the handle that sits between your front seats (or the hand brake pedal under the dash in some cars). Pulling the handle pulls the cable, which engages the hand brake assembly and pushes a pair of brake shoes into contact with the inside of the drum.
However, despite that simplicity, several things could go wrong with your hand brake. The most common issue is simply that you need to adjust your brake shoes. However, there could be a problem with the cable (corrosion or wear, for instance), or there could be a problem with the handle itself, although this is rare.
Common reasons for this to happen:
- Need to Adjust Brake Shoes: The single most common reason your hand brake won’t engage is a need to adjust the brake shoes. This requires removing the rear wheels, removing the drum, and then adjusting the wheel to spread the shoes apart. Both sides should be adjusted.
- Cable Is Detached: Another potential reason here is that the cable may have come loose from one or both sides. The cable must attach to both rear brakes for your hand brake to work (if it attaches to just one side, the brake will engage but feel loose, and the car will roll on a hill).
- Cable Is Loose at the Handle: A much less common problem is that the nut where the cable attaches under the handle is loose. There will be slack in the cable if this happens, and pulling the handle will not engage the hand brake. This is most common after inexpert parking brake repairs.
- Rusted Bell Crank: The bell crank is really nothing more than a lever that sits near the front of the hand brake assembly. These are prone to rust, particularly if you don’t use your hand brake very often. If this is the case, your hand brake will not engage.
What to expect:
One of our experienced mobile mechanics will come to your home or office and inspect the entire hand brake system, from the handle to the bell crank, the cabling and the attachment points at the rear. The mechanic will also provide you with a full report that details the scope and cost of any necessary parts and repairs.
How it’s done:
The mechanic will inspect all aspects of your hand brake, beginning with the handle or pedal in the cabin. The mechanic will also inspect the cables, the shoe condition and adjustment and other aspects of your hand brake system. It may be necessary to remove one or both rear wheels and the brake drums (if your car has drum brakes). If your car has disc brakes, the caliper and rotor may need to be removed to inspect the hand brake shoes, which are located inside the built-in drum on the rotor itself.
How important is this service?
If your hand brake does not engage, it will not prevent you from driving, but it does make parking on an incline risky. The transmission may slip out of park, and the vehicle will roll down the slope. One of our mechanics can fully assess your hand brake and advise you on what is needed to repair it.
