Chevy Astro Brake Problems

by Andy Joseph

The Chevrolet Astro--a van produced by General Motors from 1985 to 2005--was beset by a host of problems. Chief among these involves its anti-lock braking system.

BPMV Assembly

The most common and severe brake problem that affects the Chevy Astro is failure of the brake pressure modulator valve (BPMV), which may cause the pedal to drop. This problem is most common with the 1991 to 1993 Astros although they are known to occur in many of the Astros produced throughout the 1990s.

Wheel Sensors

Faulty wheel sensors are also common with most model-year entries of the Astro's last decade of production (1995 to 2005). However, in some cases, the problem can be fixed without replacing the sensors by resetting them.


As of September 2010, the cost to repair the BPMV assembly is approximately $800 for parts and $130 for labor. If the wheel sensors need to be replaced, this can range from $75 to $102 in parts, depending on whether the van has two-wheel or four-wheel drive; the labor cost is estimated at $80.
