Troubleshooting Braking System In A Mini Truck

Troubleshooting the braking system of a mini truck may be a daunting task, especially to those with no experience. For one to perfectly perform it, you must be knowledgeable about what you are doing. Troubleshooting involves the identification of the problem and coming up with a possible solution to this problem. You can diagnose the braking issue of your mini truck by giving it a systematic approach referred to as the elimination process. The elimination process involves identifying and solving the most common problem and advancing to the most complex one. This guide will address two common ways of troubleshooting braking system in a mini truck and have the vehicle back in form.

Troubleshooting Braking System In A Mini Truck

Here are two common ways to troubleshoot a mini truck braking system.

Dragging Brakes

Dragging or brakes hanging up happens when they fail to disengage. You will notice this when you feel a burning smell when applying brakes. It is hazardous to drive when your brakes are hanging as it can damage your minitruck. 

The caliper can drag brakes if they rust due to salt used during winter and when they are old. It is easy to change brake calipers, and the process cannot take more than one hour. You can avoid this problem by not driving your minitruck in pools of water and areas where salt has been used to clear roads. If this doesn’t offer a solution, always clean your wheels and underneath of your minitruck after every winter season.

When the fluid return hole in the master cylinder is dirty, all four wheels of your mini truck will drag. This is because the brake fluid will not effectively function by either not returning or not being able to release the excess pressure it goes to the wheels with. Use denatured alcohol and wire to clean up the hole. 

Failing Brakes

Brake failure is a common problem that is experienced up to date. However, technology has advanced to curb a complete brake failure on your minitruck. The master cylinder has two seals and pistons that control both front and back brakes. These two pistons and seals do their work independently so that only front or rear brakes can be affected in case of brake failure. Brake failure can be felt when the brake pedals are soft or hard.

When the Pedals are Soft, they will quickly move to the floor without stopping your minitruck. If this happens, check if the brake fluid is leaking, as this might reduce the level of the brake fluid. Check if there is air in the hydraulic brake system as this can make the brake pads soft.

When Brake Pedals are hard, you will use a lot of energy to press them to the floor. At times they might resist when you press them. It happens when the power boost system is faulty. In this case, check if the valve or the vacuum hose is in good condition. 


As an owner of a minitruck, it is necessary to equip yourself with the primary brake troubleshooting mechanisms that will bail you out if you experience any braking problem. When your brakes have started developing problems, never depend on troubleshooting, but you should visit a mechanic for a thorough brake checkup.
