  6. Rotors Getting HOT

    in Suspension & Brakes

    Posted · Edited by skrlin (see edit history)

    Just had a quick question my brakes on my SSS get into temps of 250F almost 300F in the rear with normal driving, I also noticed stress cracks on my rear rotors from excessive heat. Just recently I took apart the rears to install pads to find the drivers side caliper sliding pin to be stuck, fixed it up installed new grease yada yada. I also removed the parking brake lines/drum style assembly to elimate any other drag on the system. Also noticed with the increased temps that the grease for the sliding pins/contact points is turning orange from the heat! I have not bled the system yet but curious as to know if air in the system might cause a drag on the brakes causing my rotors to get HOT. Would like some insight on this, could this be a proportioning valve/master cylinder issues as well? All input is greatly appreciated. Thanks.

    Thanks Blown 346, I noticed you are in Rockford, Plainfield here. I just hate like hell to replace the throttle body and find out its not causing the P1516, will check grounds this week and will get plugs, wires, filter and new fluid for tranny from the dealer, can get stuff for cost.

    No check engine light at all. O2s are orginal. Like I said only check engine light I get is when I set the cruise and then I get reduced engine power, which the scan shows P1516, this eventually clears out after like a couple restarts.

    I have a good feeling that its has nothing to do with the components but the fact its sluggish and I have to give it more gas to keep up IE the mis match between the throttle. Will try the seafoam. I will check the grounds as well. Is there a specific one that causes problems? I know my in cab microphone/speaker for onstar rattles. Makes me believe possible ground issue. I know I tried to remove the fuel filter a while back and def had no luck. I know at the same time I cleaned out the throttle body as well.

    Did plugs and wires at 100k all with OEM parts. Truck has been sluggish. Noticed when trans is cold I do have hard shifts. I know I have a bad rim which I think is causing the vibration. Trans fluid from the stick looks good. Maybe i need to drop the pan and really look. could this be possible slippage in the trans?

    Long time member. Anyways, I have an 03 SS, had it from 24k miles, today it has 181,xxx just recently my MPG has gone down dramatically. Today just crusing around with light throttle MPG was showing a best of only 10-12 Mpg, again this is very light throttle, Also I have been getting a code P1516, I seem to be getting this when I engage cruise control. I use cruise control for my out of state business trips. Also I have a slight vibration around 60-70mph. Any help on this would be greatly appreciated. Truck has been maintained and serviced throughtout its mileage.

     

    Thanks.
