I have a 2007 Chevy Suburban LTZ 4 WD with 5.3 liter V8 motor. Recently after I replaced the right front brake caliper and hose because the right brake was dragging we have had 3 mesages come across info screen. They are: Service Brake System, Traction Control is off and The Parking Brake indicator light is on all simultaneously. I have no idea where to start looking for this. I have 6 vehicles in the family 3 GM products, 1 Honda, 1 Ford and 1 Toyota Scion is there on diagnostic computer I can get to work on all 6 that is reasonably priced? The Ford car is a 2001 Mustang GT and I want to be able to govern that motor back for my teeage driver then be able to open it up when Dad wants to play. Priority is to answer the Suburban question then deal with the others.Thanks

Hello, I'm Cam. Please include all the details about your issue so I can accurately advise you. I cannot see your vehicle so please be detailed.
I can answer the Chevy question here.
First off, the recent repairs and combination of lights suggests a wheel speed sensor. All will set if there is a wiring issue to the wheel speed sensor and the proximity of the sensor and wiring in relation to the repairs makes that the first place to look.
Check the wiring that runs from the body, along the upper control arm to the sensor in the front wheel bearing. Is there damage to the wiring?
A connector disconnected?
Can you see my last reply with my first set of suggestions?
I started by checking the brake fluid in the resevoir and it was actually low. Surprised me unless I have a leak under pressure. Have not had time to check that. I filled the resevoir and test drove the vehicle and none of the 3 warning messages have shown up. Could this have been the problem or is this going to be one of those intermittent issues that may be hard to solve???
Usually only the red brake warning light will come on when the fluid is low so I would not say this is done yet. If they feel normal then for now, but do the visual inspection of the wheel speed sensors and see what happens.
