How To Compress Brake Caliper With C Clamp?

If you drive a car, you must have encountered situations wherein the vehicle brakes failed to operate in the right manner. It is most likely to happen once you take your feet off the pedal. You are likely to experience that the vehicle is tending to move in different directions once you hit the car brake. These situations challenge the car’s function and make you vulnerable to catch severe accidents in the course of driving. It is a clear indication that the brake caliper is facing some crucial issues with the compressor. The paragraphs underneath shall discuss the critical points in that regard.

How To Free A Stuck Brake Caliper Piston?

What Causes A Brake Caliper To Stick?

The most crucial question that will spring up in this context is why the brake caliper seizes to function correctly. Here are the most vital points relevant to account in that regard:

1. Caliper bolts moving apart

The first and foremost factor beyond this problem is the malfunction with the caliper bolt. Your vehicle is likely to encounter these issues when these units tend to move apart. If you notice these instances, you need to ensure adequate lubrication to address the problem. 

2. Sticky Piston

it is another common factor to trigger issues with the brake caliper. If there are deformations in the Piston’s shape, the seal uncoils to create such issues. It results in compression of the Piston. In case the Piston is not sliding in the right manner, there will be issues with the Piston’s compression.

3. Automobile Immobility

If the car is standing still for long at a go, compression issues will come up. It happens as the immobile vehicle stands more vulnerable to catch rust along the brake caliper region, preventing the usual compression function. 

How To Compress Brake Caliper With C Clamp

Step 1: Looking over the inner side of the brake caliper, you will find a cylindrical piston. It features a high degree of flexibility that allows the Piston to adjust itself with the vehicle brake pad. Hence, before you try to compress the brake caliper, the cylinder requires readjustment with the brake’s rotor. 

Step 2: You will also find a reservoir for the brake fluid. Now, you need to eliminate the covering cap. Unless you remove this cap, you will experience excessive pressure once you initiate the caliper compressor. 

Step 3: It would help if you positioned the C-Clamp terminal against the cylindrical Piston, covering the caliper. Ideally, you should fix its screw on the top of the caliper. You can utilize a small piece of wood for shielding the piston surface. Now, you need to keep turning the screw. You should ensure that you are doing it gently. Consequently, you can enhance the pressure, compressing the Piston as per your needs. 

Please note that you should gradually screw up the area until you insert a new pad on the caliper. Consequently, it would be best if you connected brake pads with the caliper. At this stage, you are over with your assignment to compress the brake caliper. It would be best to put on the fluid reservoir’s cap to ensure that no dust and debris are moving inside. 

Tricks And Tips About Compressing The Brake Caliper

Before getting into the action, you should clean the Piston thoroughly. To ensure that the caliper functions to the optimum extent, you should add a little bit of grease to it. In case you observe the Piston offer no resistance when you try to compress it, understand that you need to go back a few steps. In these situations, you need to use the caliper tool. This tool is available with online and offline stores. 

It is essential to ensure that the fluid reservoir cap has been firmly locked. In case water or dust is coming in contact with the brake fluid, it is likely to intensify the trouble further. To ensure that the situation does not take such unsolicited instances, you should not mind investing a little additional effort and time. 

In case you find it difficult to move the brake pad, you need to utilize a hammer to accomplish this task. It will help if you gently hit the brake pad. Consequently, you will need to replace the bolts and pins that hold the brake pads. 

Once you have completed these steps, you need to check if you feel it hard to press the brake or not. In case you still experience troubles, you need to work on the component unless it becomes effortless to press the car brake.

Once you have assembled back all the car components, you should ideally go for a round of test drives to explore if the car is in the right driving condition.
