Peterbilt 325 Disc Brake Pads in US

Disc brake pads are the most frequently replaced component in your Peterbilt 325 braking system. The friction material your 325 calipers press against the rotor surface wears down with every stop, and the right pad formulation for your Peterbilt 325, your driving style, and American climate directly affects your stopping distance, rotor lifespan, brake noise, and dust output.

What Are Disc Brake Pads on the Peterbilt 325

A Peterbilt 325 disc brake pad is a steel backing plate bonded to a friction material compound. When you press the brake pedal on your 325, hydraulic pressure forces the caliper pistons to squeeze the pads against the spinning rotor, converting kinetic energy into heat and slowing your Peterbilt 325. The friction material wears gradually and must be replaced when it reaches the minimum safe thickness, typically 3mm, to maintain full stopping performance on your 325.

Signs Your Peterbilt 325 Disc Brake Pads Need Replacing

• Squealing or squeaking from your Peterbilt 325 when applying the brakes, wear indicator contacting the rotor
• Grinding, metal-on-metal sound from the 325 indicating pads are fully worn through
• Longer stopping distances than normal for your Peterbilt 325
• 325 brake pedal requires more pressure than usual or feels soft underfoot
• Steering wheel or seat vibration on your Peterbilt 325 during braking
• Visible pad thickness below 3mm on your 325 when viewed through the wheel spokes

Ceramic vs. Semi-Metallic Pads for the Peterbilt 325

Ceramic Brake Pads for the Peterbilt 325

Ceramic pads are the premium everyday choice for most Peterbilt 325 drivers. Formulated from a dense ceramic compound, 325 ceramic pads maintain consistent friction effectiveness across a wide temperature range, including cold starts on your Peterbilt 325 at sub-zero temperatures. They produce minimal dust, run quieter in stop-and-go city traffic on the 325, and are significantly gentler on Peterbilt 325 rotor surfaces than metallic alternatives.

Semi-Metallic Brake Pads for the Peterbilt 325

Semi-metallic pads excel under sustained heat loads on the Peterbilt 325. They are the preferred choice for 325 trucks and SUVs used for towing, and performance Peterbilt 325 vehicles where braking generates high sustained temperatures. Semi-metallic pads provide more aggressive stopping bite at high temperatures on your Peterbilt 325, at the cost of slightly more noise and dust in everyday driving.

Frequently Asked Questions - Peterbilt 325 Disc Brake Pads

How often should I replace my Peterbilt 325 disc brake pads?

Most Peterbilt 325 brake pads last between 40,000 and 70,000 kilometres, but this varies based on driving style and conditions. American city driving tends to wear 325 pads faster than highway driving. Inspect Peterbilt 325 pads at every oil change and replace when friction material reaches 3mm or less.

Should I replace front and rear brake pads on my Peterbilt 325 at the same time?

Not necessarily. Front brakes on the Peterbilt 325 handle 60 to 70 percent of braking force and typically wear faster. Always replace pads as an axle pair on the 325, both left and right on the same axle, to maintain even braking force.

Are ceramic or semi-metallic pads better for my Peterbilt 325 in American winters?

Ceramic pads are the better everyday choice for most Peterbilt 325 drivers. For 325 drivers who tow regularly or drive performance Peterbilt 325 vehicles, semi-metallic pads deliver superior stopping bite and heat resistance under demanding conditions.
