A handbrake, also known as a parking brake, is a crucial safety feature in vehicles. It serves to keep the vehicle stationary when parked, preventing it from rolling unexpectedly. The brake shoes within the handbrake system play a vital role in this process. However, if these brake shoes are installed incorrectly, it can lead to a variety of issues. As a reputable handbrake brake shoes supplier, we are well - versed in the signs that indicate a faulty handbrake brake shoe installation.
1. Excessive Handbrake Travel
One of the most noticeable signs of a faulty handbrake brake shoe installation is excessive handbrake travel. When you pull the handbrake lever, it should engage the brake shoes with a certain amount of resistance and stop the vehicle from moving. But if the brake shoes are not installed properly, you may find that you need to pull the lever much further than usual before the handbrake starts to have an effect.
This excessive travel can be due to several reasons related to the installation. For example, the brake shoes may not be adjusted correctly. If they are set too far from the brake drum, more movement of the handbrake lever is required to bring them into contact with the drum and create the necessary friction to hold the vehicle. Another possibility is that the return springs, which are responsible for pulling the brake shoes back when the handbrake is released, are either misaligned or damaged during installation. This can prevent the brake shoes from returning to their proper position, leading to increased travel.
2. Uneven Braking
Uneven braking is another clear indication of a faulty handbrake brake shoe installation. When the handbrake is engaged, all wheels should be held firmly and equally. However, if the brake shoes are not installed correctly, one or more wheels may experience different levels of braking force.
This can manifest in several ways. For instance, when you park on a slope, the vehicle may seem to tilt or pull to one side, indicating that the handbrake is not evenly distributed across all wheels. In some cases, you may also notice that one wheel locks up while others continue to rotate slightly when the handbrake is applied. Uneven installation of the brake shoes, such as improper positioning or incorrect adjustment of the tension on each side, can cause this problem. It not only affects the effectiveness of the handbrake but also poses a safety risk, as the vehicle may not be held securely in place.
3. Noise During Handbrake Operation
Unusual noises during handbrake operation are often a sign of a problem with the brake shoe installation. These noises can range from squealing and grinding to rattling sounds.
Squealing noises are typically caused by the brake shoes rubbing against the brake drum in an improper manner. This could be due to the brake shoes being installed at an incorrect angle, causing uneven contact with the drum. The friction between the misaligned brake shoe and the drum generates high - pitched sounds. Grinding noises, on the other hand, are more serious and may indicate that the brake shoes are worn down or that there is debris trapped between the shoe and the drum. This can happen if the installation area was not properly cleaned before fitting the brake shoes. Rattling sounds may suggest that the brake shoes are loose or that the mounting hardware was not tightened correctly during installation.
4. Handbrake Warning Light
In modern vehicles, the handbrake warning light on the dashboard is designed to alert the driver when there is an issue with the handbrake system. If the brake shoes are installed incorrectly, this warning light may illuminate.
The warning light can be triggered by a variety of installation - related problems. For example, if the handbrake switch, which is responsible for sending a signal to the dashboard when the handbrake is engaged or disengaged, is misaligned during installation, it may send an incorrect signal to the vehicle's computer system. This can cause the warning light to come on even when the handbrake is functioning normally. Additionally, if the brake shoes are not making proper contact with the drum, the vehicle's sensors may detect a problem and activate the warning light.
5. Difficulty in Releasing the Handbrake
A faulty handbrake brake shoe installation can also make it difficult to release the handbrake. When you try to lower the handbrake lever, it may feel stiff or require more force than usual.
This problem can be caused by several factors related to the installation. The return springs, as mentioned earlier, may be misaligned or damaged, preventing the brake shoes from returning to their original position. In some cases, the brake shoes may be stuck to the brake drum due to improper lubrication or the presence of rust and debris. If the brake shoes are installed too tightly against the drum, they may also create excessive friction, making it hard to release the handbrake.
