Why My Truck Jerks When Braking?

Hey, has anybody here experienced having their truck jerks when braking forward a bit sometimes after stopping completely from braking? Like, say you’re completely stopped at a red light, then let go of the brakes, and it jerks forward a little? Mine does this occasionally, and I’m wondering if it’s normal or not? Just get through the article to find the solution to it.

Take the issue of air brake systems, for instance. Most managers and drivers have a general understanding of how these specialised friction brakes work but not thoroughly enough to grasp the trustworthy mechanics of this critical safety system.

How Do The Truck Brakes Work?

Air brakes work using compressed air instead of hydraulic fluid. The air compressor then pumps the air into the air storage tanks, which store the compressed air until it’s needed. Air pressure is used to apply the service brakes and release the parking brake.

Air brakes are typically used on heavy trucks and buses. The system consists of service brakes, parking brakes, a control pedal, and an air storage tank. A disc or drum arrangement is designed to be held in the applied position by spring pressure for the parking brake.

What Make Truck To Jerk When Braking?

Here are the causes for your truck jerks when braking.

1. Transmission Trouble:

Suppose you’re a part of a bit of a group of car owners with a manual transmission, the occasional jerk while shifting isn’t uncommon. Sometimes, the driving force doesn’t time the discharge of the clutch with each shift, causing the vehicle to jerk.

If you downshift from a high to a lower gear from fifth to second, your car may jerk significantly if you haven’t reduced your speed. By practising controlled downshifts, you’ll find the matter has nothing to try to do with the brakes but lies in your driving style.

2. Brake Check:

Unsurprisingly, a truck jerks when braking if there’s a drag with the brakes. Typically, brakes will squeal, squeak or grind, particularly with warped rotors. Further, you’ll feel some vibration as you apply the brakes, causing a slight jerk to the vehicle as you come to a stop. The problem may only be air within the brake lines.

3. Inspect ABS:

Usually, when the ABS is malfunctioning, a red light switches on within the control panel. Faulty sensor wiring or metal shavings, or other debris could also be contributing problems, the latter causing false feedback. Use an ABS scan tool to see fault codes, which can identify the matter. Finally, when the work is completed, the fault code should disappear. Otherwise, you can clear it together with your diagnostic tool.

4. Worn Calipers

This problem occurs in cars with high mileage or in vehicles where maintenance was inadequate. Calipers wear off as time passes, and that they will become loose.

5. Rusted Discs:

You have probably noticed that a bit of layer of rust will form on the brake discs if you do not drive for a more extended period. This is often very true if you reside in a neighbourhood with high humidity.

The simplest solution isn’t to let the car sit too long without driving it. If you are doing this, then the rust layer will be consistent, making us choose the costlier solution, that of adjusting discs. You’ll choose the answer presented within the video above, but it’s not recommended.

6. Worn Pads

One of the foremost common causes, worn restraint, can cause the car to jerk when braking. Other signs that confirm brake pad wear are the whistling they emit once you brake and, therefore, the squeaks, which are special metal antennae that rub against the discs, causing a squeak and thereby signalling the car owner that it’s time to vary the restraint.

7. Sticking Calipers

The explanation for the calipers is rare. However, this problem also caused the car to jerk not only braking but also while driving.

What To Do If My Truck Jerks When Braking?

Here are the checks and replacements that need to be done.

1. Air Removal In Brakes:

If that’s the case, use a brake bleeder kit to bleed the brakes. You’ll also get to replace the restraint and replace or resurface worn rotors. While you’re at it, check the tires to make sure sufficient tread remains, then rotate them as required. Lastly, inspect the love handle to make sure it’s adequate air.

2. ABS Checks:

Today’s vehicles have antilock brake systems (ABS), which help your vehicle come to a secure stop, especially in slippery conditions. Specifically, the tactic includes sensors, an electronic control module, and a hydraulic control unit.

Always follow your owner’s manual to schedule maintenance items at the proper intervals. Handling simple tasks early can assist you in avoiding more significant issues later, including brake problems.

3. Solving Caliper Troubles

In worn Brake calipers, the repair isn’t possible. It might be best if you changed the calipers. Remember to lubricate the new parts after installing them. A unique brake lining material is attached to the brake shoes to help promote consistency.

If the lining is a good fit, it should also regulate the heat created from friction. For a sticky caliper, you would like to see the pads and, therefore, the calipers. In most cases, the sticky caliper will need replacement to avoid your truck jerks when braking.

4. Clearing Rusty Rotor

If the rust layer is fragile, it’ll disappear naturally once you drive and brake for the primary 12-18 miles. This may cause the car to jerks once you brake. You would like to vary the brake pads and rotor to high-quality ones. Also, you can use WD-40 for removing the dirt, rust, and stinky substances in the brakes.


I hope you found a solution for truck jerks when braking by following the procedures and precautions described in the article. Get used to fix on your own, which can improve your skills.
