Can power steering affect brakes?
The power steering pump does supply power to both the steering and brakes. But usually, applying the brakes robs power from the steering (stand on the brake pedal and try to turn the wheels when standing still). Your issue may be a problem with power steering pressure, or the hydroboost unit may be going bad on you.
Can a bad Hydroboost affect steering?
Hydroboost brake units use power steering pressure instead of engine vacuum for brake assist. A failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering gear.
What should you do if your power steering or power brakes fail?
If power steering failure is accompanied by power-brake failure, you will have to push down hard on the brake pedal to slow the vehicle. Do not panic if your power steering cuts out, simply ease off the accelerator and gently steer the vehicle to the side of the road.
Why does my power steering go out when I brake?
Low Fluid Level Hydraulic fluid transfers force from your steering wheel to your car’s wheels. This additional force greatly reduces the amount of effort you must supply when turning your car. Also like your brakes, the power steering system may fail to work properly if its fluid levels become excessively low.
How do I know if my hydro-boost is bad?
The common signs of a bad hydroboost include less braking power, a brake pedal that is hard to press, and fluid leaks.

How does the brake light work on a GMC C6500?
The low air pressure switch turns on the PRIMARY BRAKE warning lamp when the engine is started, and the lamp remains on until the system reaches normal pressure. If the system air pressure drops below 503 kPa (73 psi), when the ignition is on, the low air pressure switch turns on the warning lamp and the module sounds a constant tone alarm.
When does the brake warning light turn on?
Upon startup, all the warning indicators will turn on as a bulb check. This module turns on the PRIMARY BRAKE warning lamp on the instrument panel when the fluid level in the brake master cylinder is low, or when the flow of fluid from the power steering pump is low.
