TheGeorgiaKid Posted December 6, 2008 Report Share Posted December 6, 2008 Does any one have the rear disk setup from their AWD SS that they want to sell that have upgraded to aftermarket?? I want to change my '06 to disk in the back & don't really want to spend the money for Baer or the Z06 setup. Also were the stock rear calipers on AWD SS's single or dual piston? If you're asking why I want to do this. I like the look of front & rear disk brakes, plus I like disk brakes better. Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted December 8, 2008 Report Share Posted December 8, 2008 the rears were single piston... all you need to do is buy the backing plates/e brake assembly off someone and get some powerslots or used baers. once you have the backing plates, any setup fits. btw, the drums on your truck work much better as far as stopping power goes. but it sounds like you know that, you want the look lol.

kevinh Posted December 8, 2008 Report Share Posted December 8, 2008 the rears were single piston... The rear caliper is a dual piston on my 2004 SSS and if I"m not wrong 2003 to 2005 Allwheel Drive SSS were that way, they came with the Heavy duty brakes off the 2500 models.

I agree that the drum brakes are very good. To me a SS is like the Corvette of trucks & vettes have 4 wheel disk brakes, so I think the vette of trucks should too. Would I have to change the e brake cables too, are they different length & the hard brake lines are different, what about the proportioning valve is it different? My parents have a '03 1500HD with 4 wheel disk brakes with dual piston calipers front & rear. I almost think the brakes are just as good or a little better than my SS.

70chevy03ss Posted December 8, 2008 Report Share Posted December 8, 2008 Yeah if I were you I would do an upgraded rear setup. I have 2500HD suburan calipers on mine. The rears do most of the stoping and wear out faster. Thats why in 05 the switched back the tried and true disk drum.. Quote Link to comment Share on other sites More sharing options...

Did you have to change the mounting brackets or did the 2500HD calipers bolt right on? The '03 1500HD we have as 60000 miles on it on the original rear pads & there is still plenty of pad left. That's sayin something I think. Quote Link to comment Share on other sites More sharing options...
70chevy03ss Posted December 9, 2008 Report Share Posted December 9, 2008 No I had 2 piston calipers from day one. My pops works at NAPA and thats what they could come up with. I will tell you this I have a 1970 chevelle I have not once changed the rear pads. I have disk in front and drum rear. And they have alot of pad left. Also I have a 1988 GMC with well over 300,000. changed the rears once maybe twice because we had to change out the rear end. I am telling you. These trucks are heavy and most of the braking is done in the rear not the front. The only thing i can say is upgrade to the big 4 piston corvette calipers and and pads like I'm doing and it will help. Other then that slap some fresh paint on the drums and your good to go. like I said its my .02No I had 2 piston calipers from day one. My pops works at NAPA and thats what they could come up with.

04CHASE Posted December 9, 2008 Report Share Posted December 9, 2008 kind of swapping topics but rey is somewhat correct. alot depends on the abs system which is usaully tied into the proportioning valve which will determine how much of the brake pressure is applied without locking up . i have never dont the brakes on my truck however, only the aftermarket alumasports which wore evenly .
