From 5- and 6-lug C10 pickups to heavier 8-lug C20 and C30 trucks, this generation calls for brake parts matched to the way each truck is configured. Explore front and rear disc conversions, power brake systems, master cylinders, hydraulic controls, brake lines, calipers, rotors, drums, and related components for 1967-72 Chevy trucks.
Brake Options for 1967-72 Chevy and GMC Trucks
Lug pattern acts almost like a fork in the road on a 1967-72 Chevy or GMC truck. A 5-lug C10, a 6-lug C10, and an 8-lug C20 or C30 may share the same basic body generation, but their brake builds quickly separate once the hubs and wheels enter the picture.
For C10s, that choice can also affect stance. Stock-spindle systems keep the existing front height, while drop-spindle conversions lower the truck as the drums give way to discs. Wilwood configurations create another route for builds where the caliper package itself is part of the upgrade.
Move into C20 and C30 territory and the half-ton choices no longer apply. Dedicated 8-lug systems retain the heavier-duty wheel arrangement, keeping those trucks on a brake path designed around their own hubs and front-end hardware.
The 1971-72 trucks add a rear dimension through 5-lug C10 disc conversions and matching parking-brake components. Power assistance remains independent of those wheel-end choices, with conventional, BlackOut, and Wilwood-based booster systems available, along with the master cylinders, valves, lines, and fittings that connect the finished brake system.
FAQ
How do I choose brake parts for my 1967-72 Chevy C10, C20, or C30?
Begin by identifying the exact model year and whether the truck is a C10, C20, or C30. Then check the wheel lug pattern, spindle setup, front and rear brakes, rear axle, master cylinder, and whether the truck uses manual or power brakes. These details matter because the collection includes different systems for 5-, 6-, and 8-lug applications.
Can I keep a 6-lug wheel pattern when converting my C10 to front disc brakes?
Yes. POL offers 6-lug front disc brake options for compatible C10 applications, along with separate 6-lug conversion rotors. There are also 5-lug configurations, so decide whether the truck will retain its existing wheel pattern or change to another setup before selecting the front brakes.
Should I choose stock or drop spindles for my C10 disc brake conversion?
That depends on whether changing front ride height is part of the project. POL carries front disc conversions compatible with stock or drop spindle configurations. If you plan to lower the truck, choosing the spindle and brake package together can help avoid buying components that do not match the final suspension setup.
Are 8-lug disc brake conversions available for C20 and C30 trucks?
Yes. POL lists a Deluxe 8-lug front disc conversion for 1963-70 Chevy and GMC C20/C30 trucks, covering the 1967-70 portion of this collection. C20 and C30 owners should verify the exact year, hub and axle configuration, wheel pattern, and wheel clearance before selecting a system.
Can I convert the rear brakes on a 1971-72 C10 to discs?
POL carries a rear 5-lug disc brake conversion covering 1971-87 C10 trucks, so 1971-72 applications fall within its listed range. Before ordering, confirm the rear axle, lug pattern, axle specifications, parking-brake requirements, and available wheel clearance.
What power brake options are available for 1967-72 Chevy trucks?
The collection includes a standard 1967-72 Chevy/GMC truck power brake booster kit, a BlackOut booster with POL or Wilwood master cylinder options, and a BlackOut 2.0 conversion with a Wilwood master cylinder. Booster pushrods, boots, vacuum hoses, and related components are also available separately.
What should I check before ordering a complete brake conversion?
Confirm the truck series, exact year, 5-, 6-, or 8-lug pattern, spindle configuration, desired ride height, front and rear brakes, rear axle, wheel clearance, master cylinder, proportioning setup, and brake assist. Also check exactly what the selected kit includes, since this collection ranges from individual service parts to more complete conversion systems.
