check the switch at the top of the brake peddle.
The power brake reduces the driver's effort to brake by enlisting the engine to boost brake pressure. The Power Brake system is designed in such a way that should the engine fail, the brake will still work one more time.

An engine brake, also known as a compression brake or Jake brake, is a system in a vehicle that helps slow down the vehicle by using the engine's compression to create resistance. When activated, the engine brake closes off the engine's intake valves, which restricts the flow of air into the cylinders. This causes the engine to work against itself, slowing down the vehicle without using the vehicle's brakes.
Open your hood up and check your brake fluid reservoir.. it should be in the upper right of the engine compartment.. it's not hard to miss... check your level.

The 1991 Volvo brake light relay switch is located beneath the drivers side dashboard. The brake light relay switch will be above the brake pedal.
