Carefully remove the cap and inspect the fluid level, ensuring it falls within the recommended range. If the fluid level is low, refill it with the recommended brake fluid type.

Replace Worn Brake Pads Or Shoes

Brake pads or shoes that have worn out significantly will compromise the braking effectiveness of your tractor trailer. It’s important to replace them promptly to ensure safety on the road. When inspecting the brake pads or shoes, look for indicators such as thinning or uneven wear, cracking, or loss of material. If any of these signs are present, it’s time to replace them. Refer to your tractor trailer’s manual or seek professional assistance to ensure you select the correct brake pads or shoes for your specific model.

By adhering to these regular maintenance tips for tractor trailer brakes—inspecting brake components regularly, checking brake fluid levels, and replacing worn brake pads or shoes—you can ensure optimal brake performance and enhance road safety.
