Question about 1999 GMC Suburban
I have a 1999 GMC Suburban and the breaklight keeps coming on and the breaks lock when I turn left and hit the breaks.
By brakelight I am going to assume you mean the warning indicator on the dash. Not sure if you are planning to do the work yourself or if you are just looking to find out the probable cause. Here are some things to look at to narrow down the exact problem but you are definitely going to need at least a front wheel brake job. I would suggest that you replace the pads, calipers and rotors when doing this since the problem has gone this far.
You most likely have a leaking front caliper that is causing these problems.
Is the brake fluid low in the master cylinder?
Remove the front tires and do a visual inspectioninspection of the braking components.
1) Check for any visable leaks, a leaking caliper will cause the brakes to grab and lock up.
2) Spin the rotors, they should spin freely without grabbing, there will be a slight drag from the brakes. Both sides should be equal. Grabbing rotors can indicate a warped rotor which can also cause the brakes to lock up.
3) Is there plenty of bake pad remaining? You need to have a minimum of 1/4" pad remaining though more is prefered. Low pads can allow the piston to come out of the caliper farther than designed and not allow the piston to retract properly.
If you would like assistance on how to do these repairs just reply to this message and I will help you out.
