Why is the handbrake not holding?
3 Answers
The reason the handbrake is not holding is due to severely worn brake pads, which need to be replaced. If the brake pads are fine, then the handbrake cable may have stretched and requires adjustment. Below are specific details about the handbrake: 1. Introduction: The professional term for the handbrake is auxiliary brake. Unlike the main braking system, it uses a steel cable connected to the rear brake shoes to apply braking force. Prolonged use of the handbrake can cause the steel cable to undergo plastic deformation. Since this deformation is irreversible, long-term use reduces its effectiveness and increases the handbrake's travel. 2. Components: It consists of a brake lever, cable, brake mechanism, and return spring, acting on the drive shaft or rear wheel brakes to stabilize the vehicle.
I've also experienced the issue of the handbrake not holding properly before. It turned out to be mainly due to loose handbrake cables. Over time, the cables can stretch, making it impossible to fully engage the brake even when pulled to the top. Additionally, it's important to check the rear brake pads. If they're worn too thin or contaminated with oil, their grip will be insufficient. Grooved or warped brake discs can also affect braking performance. In my case, I took it to the repair shop where the mechanic first tightened the adjustment nut on the cable and then replaced the brake pads. Now during every maintenance, I remind the technician to check the handbrake lever travel, ideally keeping it between 5-7 clicks. Parking on slopes is particularly risky—always test by pushing the car after engaging the handbrake, and address any rolling immediately if detected.
Parking brake failure requires a systematic approach – I learned this the hard way during a long-distance trip. First, don't panic. Check if the parking brake cable is too loose; if the car still moves when fully engaged, tighten the adjustment screw. Accumulated dust and grease in the rear calipers can cause brake shoes to slip, requiring cleaning or replacement. Sometimes severe wear on the brake drum leads to poor contact. Remember not to just replace the cable – inspect the entire braking system. Last time, I thoroughly cleaned the rear brake components and adjusted the linkage with excellent results. Also, mind your parking habits: avoid prolonged parking brake use on steep slopes as it accelerates wear. During routine maintenance, have technicians test parking brake tension as preventive care.
