Frequently Asked Questions About Freightliner FL70-FL80 Disc Brake Parts

Will these disc brake parts fit my specific FL70 or FL80 model year?

Our disc brake parts are designed to fit Freightliner FL70 and FL80 models from 1994 to 2010. However, there are variations based on your truck's specific configuration, including axle manufacturer (Meritor, Dana, or Bendix) and GAWR rating. Before ordering, check your VIN plate or axle tag for the exact axle model number. If you're unsure, contact us with your VIN and we'll help verify compatibility.

What's the difference between OEM and aftermarket brake rotors and pads?

OEM brake components meet original Freightliner specifications and typically last 80,000-120,000 miles under normal conditions. Our aftermarket options from brands like Gunite and Webb offer comparable performance at 20-30% less cost. The main differences are price and warranty length - OEM parts usually carry a 2-year warranty while quality aftermarket parts offer 1-year coverage. Both options use similar friction materials and meet DOT standards.

Can I install these brake components myself or do I need special tools?

While brake pad replacement is straightforward and requires basic hand tools, rotor replacement demands specialized equipment including a 3/4" impact wrench, proper jack stands rated for commercial vehicles, and a torque wrench capable of 450-500 ft-lbs. You'll also need a dial indicator to check rotor runout. Many customers tackle pad replacement themselves but have a shop handle rotors due to the weight (60-80 lbs each) and precision required.

How do I know when to replace rotors versus just turning them?

FL70-FL80 rotors can typically be turned 2-3 times before replacement. Minimum thickness is stamped on each rotor - usually 1.42" for most applications. If your rotors show heat cracks longer than 2 inches, deep scoring over 0.060", or measure below minimum thickness after turning, replacement is necessary. Severe pulsation or blue discoloration from overheating also indicates replacement rather than resurfacing.

Why are there different brake pad options and which should I choose?

We offer three main pad types for FL70-FL80 trucks: Standard semi-metallic pads work well for local delivery and moderate loads. Severe-duty pads contain more metallic content for frequent stopping and heavier loads but may increase rotor wear. Ceramic formula pads produce less dust and quieter operation, ideal for food service or urban delivery. Your choice depends on application - heavier loads and mountain driving need severe-duty, while stop-and-go city work benefits from ceramic.
