part # 11508133 is a bolt that goes from the 1LE front brake bracket to the 1LE spindle. Is there a GM washer that goes under that bolt ?? Or does it even need a washer? part # anybody ???

also, I have the GM bango bolts, and the GM 1LE brake hoses. I have these steel washers for the bango bolts. All other brake hoses I have seen were copper washers for the brake hose. does anybody have a GM part #, or is the steel washers OK. They are in a GM bag of 10 and say off-road use only. IS there copper available from GM?

thx

The bolts do not use washers. Go to my website www.3rdgensolutions.com I have "installed" pictures of all the 1LE front brake components.

Use copper!

 

I have gotten conflicting information on using copper or steel bango bolt washers. copper may react with the aluminim. The steel washers are directly from GM, and are thicker than copper.

I have to look at my friends TTA. that'll be the final answer

 

The rear PBR brakes I just disassembled off an 89 Formula had copper washers on them (judging by the brake dust build up, those were the original washers). I'd be hesitant to use steel washers, for fear that I'd strip the threads in the caliper before getting them to compress enough to seal. I used copper on mine.
