A wheel cylinder is a component of a hydraulic drum brake system. [1] It is located in each wheel and is usually positioned at the top of the wheel, above the shoes. Its function is to exert force onto the shoes so as to bring them into contact with the drum and stop the vehicle with friction. [2]
The four-wheel drum brakes of the previous generation were abandoned, as the third-generation G-series vans adopted front disc brakes. [ 5 ] [ 6 ] The front disc/rear drum configuration remained unchanged throughout the entire production of the model line; heavier-duty vehicles received larger brakes. [ 4 ]

As an option, Chevrolet offered the Lumina APV with load-leveling rear air springs, [8] utilizing the air compressor that inflated the rear air springs for auxiliary use with an air hose kit. The front brakes were vented discs, with drum brakes at the rear; [7] anti-lock braking (ABS) was introduced for 1992. During 1994, traction control was ...
With slight modifications, the GMT610 also adopted the front suspension of the GMT800 pickup trucks, with short-long arm front suspension (rear-wheel drive) and torsion-bar front springs (all-wheel drive). [9] In another change, four-wheel disc brakes were introduced, standardizing anti-lock brakes (ABS). [26]
Later, disc brakes were used for the front and drum brakes for the rear. However disc brakes have shown better heat dissipation and greater resistance to 'fading' and are therefore generally safer than drum brakes. So four-wheel disc brakes have become increasingly popular, replacing drums on all but the most basic vehicles. Many two-wheel ...
The four-wheel drive version had a solid front axle and used leaf springs front and rear. The two-wheel drive version came with independent front suspension and rear trailing arms, both with coil springs. Both versions used drum brakes on all four wheels until 1971, when the entire GM light truck line was fitted with front discs as standard ...
