Hey there, thanks for your question. I would replace it with a bolt. It’s easier to take off and put back on just in case you ever have to replace the cable for some reason. If you are still having trouble with this, have a certified technician, like one from YourMechanic, check the brake system and make correct adjustments or repair to the emergency brake cable.

The emergency brake bypasses your vehicle`s hydraulic brake system to lock the wheels in place. This mechanical system uses cables that are attached to the emergency brake lever. When engaged on cars with drum brakes, the cables pull another lever that puts pressure on the brake shoes to hold the vehicle.
Drum Parking Brakes
Parking brake cables attach the brake handle/pedal/lever inside the passenger compartment to the parking brake lever inside the brake drum. The lever pushes the rear secondary shoe outward, and the brake strut forces the primary forward shoe into the drum.
In most vehicles, the parking brake operates only on the rear wheels, which have reduced traction while braking. The mechanism may be a hand-operated lever, a straight pull handle located near the steering column, or a foot-operated pedal located with the other pedals.
Parking brakes are often located in one of two places – A hand lever situated between the two front seats or a smaller foot pedal just to the left of the standard brake pedal. There are two types of parking brakes installed in vehicles, caliper mounted or drum/brake shoe.
Drum brakes allow simple incorporation of a parking brake. Drum brakes are also occasionally fitted as the parking (and emergency) brake even when the rear wheels use disc brakes as the main brakes. Many rear disc braking systems use a parking brake in which the piston in the caliper is actuated by a cam or screw.
Factors that can cause short-term, early in the driving day, drum-brake lockup include dampness, or high humidity (causing light corrosion), and excessive heat.
In an emergency, the parking brake can be activated when the vehicle is moving by pressing and holding in the button. The brakes will then be applied with force in order to brake the vehicle. The braking process is canceled when the button is released or if the accelerator pedal is depressed.
Common reasons for this to happen: Need to Adjust Brake Shoes: The single most common reason your parking 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.
It`s all in the name. Some automakers call it a parking brake, while some call it an emergency brake. While calling the auxiliary brake system a parking brake implies you use it every time you park your car, the name emergency brake implies it`s only for emergencies.
The parking brake, or emergency brake, is usually attached to a car`s rear wheels. On vehicles with rear drum brakes, the parking brake is usually attached with cables to the rear brakes, as shown in Figure 14-10.
Explanation: In most vehicles, the parking brake operates on the rear wheels only. The function of the parking brake (handbrake) is to stop the vehicle from moving when it is parked or when it is stopped on a hill.
The electric parking brake system uses the brake pads and rotors in the braking system. It has control over the caliper pistons. To remove the rear brake pads, you need to compress the caliper piston first. You won`t be able to do this if parking brake is set.
Weight: Drum systems weigh less than comparable disc systems. Parking Brake: Drum brakes make a superior park brake due to the wedging action of the shoe against the drum. Once the park brake is set, any attempt to rotate the wheel causes the drum brake to grip harder (like a wedge type door stop).
The center lever parking brake (or handbrake) is the most common type of emergency brake. It consists of a lever located between the two front seats of your vehicle.
Auto manufacturers continue to use rear drum brakes for two main reasons – lower cost and less complexity. Drum brakes are less expensive to produce because they require fewer parts than disc brakes. Unlike disc brakes, drum brakes can function as both a service brake and a parking brake.
Your car`s brakes are controlled by something called a parking pawl, which is basically a device that locks up your transmission when you put your car in park. Without it, your vehicle would roll away! Like any other part of your car, the pawl can break or malfunction for any number of reasons.
Use these four steps while the engine is still running: Press down completely on the brake pedal. Pull the lever, step on the pedal, or press the parking brake button (consult your owner`s manual for the specifics for your car) Shift your automatic transmission into “Park” or put your manual transmission in gear.
With this system, an additional lever and corkscrew is added to the existing caliper piston. When the emergency brake is pulled, the lever forces the corkscrew against caliper piston, and applies the brakes, again bypassing the hydraulic braking system.
Description: Large capacity for fast venting of brake pipe to initiate emergency quick action. Available with integral microswitch for direct interfacing with electronic air brake equipment, event recorders and other safety related devices.
