Just had my motor rebuilt after hitting a pothole&busting my oil a on my 2006 Chevy HHR LS, &everything is fine with motor,but when braking the steering wheel&brake pedal shakes hard&car seems to be shaking underneath somewhere, as well. Also, brakes seem to feel as if they are going to lockup. My husband replaced front brakes,as they showed some wear, but problem is the same. We think it is the ABS not engaging or working properly, but don't know where the ABS is located&the ABS light is not on, but it did come on for about a minute the day I busted the oil pan, but nothing happened with the brakes that day. The car quietly died within 5mins&wasn't operated until the motor was rebuilt. Any help would be greatly appreciated! Where is ABS located&does anyone know what the problem may be(i.e.- ABS, ABS sensor, etc.?) Thanks! :-)

check your fuses, then check the ABS valve located beside the master cylinder and the wiring to it and finally check your speed sensor, which is located on the transmission on a 2 wheel drive and on the transfer case on a 4 wheel drive. but make sure hat your E-brake is released as it will cause these lites to come on.

The rotors are warped, need to replace them, also when the wheeles are put back on, the lug nuts need to be tourqued down to the specifications for that car, or the new rotors will warp again.

I'd be checking the sensor (ABS) at that wheel, (right front) and adjusting rear brakes to proper clearance, as well as inspect them for proper operation with wheels off.

First check your brake fluid.
Either you have a failing brake booster, or you have developed a leak in one of your brake lines. If your brake line is leaking, it should be pretty evident, i.e. oily looking substance sprayed underneath the vehicle or in the wheel wells, if the booster is leaking (the large black/silver almost bowl shaped thing directly in front of the driver under the hood against the back wall) there will most likely be fluid dripping down the firewall below it, if your brake fluid is extremely low/empty, you probably have a leak, that could be at the booster or on a line, or even at the caliper/drum. If it is empty (which can make your ABS light, light up) then you have yourself a leak. Also, if the fluid is really low, you could try adding some, although you will have air in the lines if it was low enough to floor the brake, but you might be able to find the leak if you refill the fluid and cause it to spray from the leak again. Have someone watch under the vehicle while you do this.
