How to Troubleshoot Brakes on a Dodge Diesel
The brakes on your Dodge diesel feature a caliper and rotor design. This ensures maximum clamping force and optimum stopping power. Over time, these brakes will require maintenance. Properly maintaining your brakes will ensure your brake system performs as it should. Replacement brake parts can normally be purchased through most auto parts stores. However, troubleshooting the brakes is critical before replacing any parts.

Check for steering wheel vibration when pressing on the brakes. Any feedback in the steering wheel during braking indicates the brake rotor surface is uneven and needs to be replaced.

2
Check the brake pad wear. The brake pads should be at least 1/8 inch thick. If they are not, the brake pads need to be replaced.

Press on the brake pedal. If it feels spongy, there is air in your diesel's brake lines, and the system must be professionally bled of all air.

Open the hood and check the brake master cylinder reservoir fluid level. The reservoir cap is marked "brake fluid." You should be able to see the brake fluid through the translucent brake fluid reservoir tank. The fluid level should be between the upper and lower marks on the outside of the reservoir tank to provide optimum braking. If it is over- or under-filled, have the brake system serviced.

Press and hold the brake pedal on your Dodge diesel. If the brake pedal slowly sinks to the floor and you lose brake pressure, your Dodge's brake master cylinder has failed and needs to be replaced.

Check for excessively difficult braking. Your Dodge diesel has a power brake booster to assist you with braking. If your brake pedal seems unusually stiff, have your brake booster serviced by a professional mechanic.
