Power Brake Relay for Select GM Applications

Standard Ignition RY1933 is a 12-volt power brake relay built for select GM vehicles, including the 2018 Buick Enclave, 2018 Chevrolet Traverse, and 2008 Chevrolet Colorado. It uses a square male connector with four male blade terminals and includes a mounting bracket for secure installation.

Key Features

  • 12-volt power brake relay for brake system control
  • Square male connector with 4 male blade terminals
  • Module function for relay-based brake system operation
  • Composite housing helps protect against heat and harsh under-hood conditions
  • Aluminum contacts support durability and long service life
  • Epoxy sealing helps resist dust, heat, and moisture
  • Manufactured in a TS16949 and ISO9001 certified facility

Detailed Description

Standard Ignition RY1933 is a replacement power brake relay engineered for vehicles that rely on a module-style relay in the brake system. The housing is made from composite material to handle severe under-hood temperatures, while aluminum contacts are used to support consistent electrical performance over time. Standard Ignition RY1933 also uses premium epoxy protection to help shield internal components from dust, heat, and moisture.

Compatible With 2018 Buick Enclave, 2018 Chevrolet Traverse, and 2008 Chevrolet Colorado. This part cross-references ACDelco 84129871 for the same application.

Common Problems This Relay Can Address

  • Brake relay electrical failure
  • Intermittent brake system module operation
  • Heat-related relay degradation in the engine bay
  • Moisture or dust intrusion at the relay housing
  • Poor terminal contact from worn relay components

Installation Notes and Tips

Verify connector style, terminal count, and voltage before installation. Standard Ignition RY1933 uses a male square connector with four blade terminals and a mounting bracket, so the replacement should match the original relay layout and mounting point. Confirm vehicle application by year, make, and model before ordering.
