Question about Chevrolet Suburban

1 Answer

I changed my front pads and rooters on my 2002 suburban and now the power steering is out?

After I finished the drivers side brakes, I got in the car, started it up and turned the wheel to the opposite lock to prepare to do the passenger side wheel. While turning the steering wheel I felt the power steering suddenly fail. Lots of what looks like brake fluid dripped out by the master cylinder. I assume this is from the pressure of pushing the pistons back to set the new pads. Brake performance and pressure are fine after changing both front pads. Fluid level looks fine in the master cylinder and power steering pump, but the power steering is dead. I assume it has something to do with the "hydro-boost" system that ties the brakes into the power steering pump.

Phil: you probably got air into the power steering fluid assist piston. Try driving your car. The air should bubble up, keep adding the correct power steering fluid.

You have air in your system, you need a helper to bleed the air out. The master cylinder is what ur brake fluid resivore is sitting on, the large round object behind it is the brake booster (looks like a squished basket ball) these will be on the fire wall driverside

Where can I find a video on changing the front passenger side brake pads on a 2002 Sable?


On youtube. Also you never change just one side you always do both or your car will pull when braking.

Steering wheel wont lock and stuck in park


In the fuse block under the drivers side rear seat check the ignition 0 fuse. In the under hood fuse block check the B/U fuse and the BTSI fuse. If the b/u fuse is blown than you would not have back up lamps.

1995 suburban the whole truck shakes when i apply the brakes and the pedal seems to pulse as it slows to a stop. I have changed the front pads calipers and rotors. no change ?


Now, did the mechanic even suggested anything about MACHiNiNG ur ROTOR brake disc before putting those brake pads? U got UNEVEN brake disc and needs MACHiNiNG to equally level the pads grip to the rotor! Do it i'm very sure of it! Taaah!

Squealing sound - front driver's side brakes


This sounds like a wear indicator( a metal tab on the brake pad) is doing its job, warning you that the brake pads need replacement soon. you can bend the wear indicators away from the rotor so they won't make contact. This will stop the annoying noise. Replace the pads and check the brakes soon. Brake pads should always be changed on both wheels at thge same time, so change the other front pads also.

Power steering and brake line location2002 Chevy Silverado 2500HD


the power steering lines are very short hoses approximately 8 inches long that go from the power steering pump down to the steering box, which is located on the frame, just below the pump. The brake lines run from the master cylinder(where you fill it with fluid on the drivers side firewall) down to the frame, and then follow the frame both directions; both to the front end and the rear end, along the drivers side frame rail, just on the inside of it. The fuel line runs along the same path to the rear.

On one of the front driver side pads there is a sensor for low pads. He either did not hook it back up or got a lose connection to it.
