Baywindow Bus Front Brake Disc - 1973-79 - TRW

This front brake disc, manufactured by TRW in Brazil, is a high-quality OEM-grade replacement for VW Baywindow buses from 1973 to 1979 fitted with the 5×112 (standard small five) stud pattern. It is also suitable for Brazilian Kombi models from 1997 to 2014, making it an excellent option for dependable, factory-correct braking performance.

What the part does & how it works

The front brake disc is the primary friction surface in the front braking system. When the brake pedal is applied, hydraulic pressure forces the caliper to clamp the brake pads against the disc faces. The resulting friction converts kinetic energy into heat, slowing the wheel and safely bringing the vehicle to a stop.

Disc quality is critical to braking consistency, pedal feel, and pad life. Poor or worn discs can cause vibration, fade, or uneven braking. This TRW-manufactured disc is precision produced to tight tolerances, ensuring stable braking, good heat dissipation, and long service life under everyday driving conditions.
