    Cadillac SLS 2001 Brake Pad replacement question

    Hi,
    I'm replacing the front brake pads on my 2001 SLS and am running into a small problem. My manual says to remove the bottom caliper mounting bolt and rotate the caliper up to pull the pads out. I went to do this and when I went to rotate the caliper up a small sensor wire gets tight and won't let it go up. I assume this is the front wheel speed sensor. My question is does this sensor need to be unplugged? If so where do I unplug it? My manual doesn't mention anyhting about this. Is there a site I can go to on the net to get a more comprehensive view of the 2001 SLS brakes?

    Thanks,
    SLS MAX

    To do the front brakes you need to remove both bolts and pull the caliper off. I think you were looking at the instructions for rear brake pad removal.

    Re: Cadillac SLS 2001 Brake Pad replacement question

    Somewhere on the front suspension arm there's a clip and connector for the pigtail from the brake wear sensor. (You do not need to replace that sensor IF the service brake light is not on). The sensor slides into a chamfer in the pad edge.

    You slide the sensor wire out from under the spring clip and carefully pry the sensor tip out of the brake pad. Apply a C-clamp to the caliper and squeeze the puck back in far enough for the caliper to loosen. Slack the top bolt, remove the bottom bolt, and rotate the caliper up and back. replace the pads and sensor in the reverse order.

    The rear brakes are similar BUT you need a special tool to turn the puck back into the caliper: it ratchets out each time you apply the parking brake and you CAN NOT squeeze the puck back in.

    Thanks Don,
    Actually, I was looking at my Haynes manual which is for Cadillac Seville and Deville and that is the way they explained it. I think I will need to get a specific manual for my car, 2001 Seville SLS.
    Thanks Again SLS MAX

    Thanks,
    Excellent advice. Once I disconnected the sensor it gave me the slack I needed. Odd that my Haynes manual did not mention any of this. I do plan on doing the rear brakes . I have a tool that I bought for my Pontiac Gran Prix long ago. Wonder if it would work. It is kind of a square grid tool used for the same thing on that car. Also, my SLS needs some antifreeze and it says you are supposed to use a special brand. Any reason not to add the Prestone that says it mixes with any brand?
    Thanks Again,
    SLS MAX

    Your service manual search should start and end with a real GM Helm Manual. www.helminc.com or ebay.

    The Prestone or Havoline (Texaco) mixes that state "GM DEXCOOL approved" or something close are perfectly OK. The name DEXCOOL is the qualifier here.

    Thanks again for the good info. I have another question about service stability system info warning. I will start a new thread for that.
