Peterbilt 352 Brake Parts & Acc.

Frequently Asked Questions About Peterbilt 352 Brake Parts & Acc.

What years and models are these brake parts compatible with?

Our Peterbilt 352 brake parts are designed to fit 352 models from 1969 through 1980. However, compatibility can vary based on specific configurations like axle type, brake system (hydraulic vs. air), and whether your truck has been modified. We recommend checking your OEM and existing part numbers before ordering, or contact our tech support team with your truck's specifications for verification.

Are these brake components DOT approved and what's the quality like?

All brake safety components we carry meet or exceed DOT standards and FMVSS regulations. We stock both OEM-quality aftermarket parts and genuine OEM components. Our aftermarket brake pads, shoes, and drums are manufactured to original specifications using premium friction materials. Look for specific brand names like Bendix, Meritor, or Gunite in product descriptions for heavy-duty commercial-grade quality.

How difficult is it to install these brake parts, and what tools do I need?

Brake component installation difficulty varies by part. Brake pads and shoes typically require basic hand tools, a brake spring tool, and 2-3 hours for experienced mechanics. Air brake chambers, slack adjusters, and brake drums may require specialized tools like drum pullers and torque wrenches. We strongly recommend professional installation for air brake system components to ensure proper adjustment and safety compliance.

What's included in brake hardware kits, and do I need to order them separately?

Brake hardware kits typically include springs, pins, bushings, clips, and retainers necessary for a complete brake job. These kits are sold separately from brake shoes and pads because many mechanics reuse existing hardware if it's in good condition. We recommend replacing hardware every other brake job or if you notice any corrosion, wear, or heat damage during inspection.

How do I know when to replace brake chambers, slack adjusters, or other air brake components?

Replace brake chambers if you notice air leaks, sluggish brake response, or uneven braking. Slack adjusters should be replaced if they won't hold adjustment, show excessive play, or if the adjustment mechanism is damaged. Check for visible damage, corrosion, or if stroke length exceeds manufacturer specifications. Annual DOT inspections will identify most issues, but regular pre-trip inspections can catch problems early.
