ok well i bought some drop spindles from forum member ksbrktracer and the quality on them ehhh not good ill post up some pics later on if i can but anyways the spindles are for a 1.25 inch rotor and i have a 1 rotor i do not want to spend money on reshipping and dont want to shed out 300 for beltechs at my local performance shop...from what i know i need to switch out my brakes brake calipers, and rotors but i have no absolute clue on what parts to buy!

i went to my local autozone and they told me theres no such thing a heavy duty half ton they were clueless told me theres only one size and only one size available for rotors for c10s which they say are the 1 inch rotors...i need help asap as my truck has been on jackstands for the past 2 days! plus my dad is reaaaaaaaally on my ass about this problem..

Buy '73 rotors and calipers.
They only come in the 1.25 hd rotor width.

Some of the confusion may come from the terminology. It's not that there is a "heavy duty" as a step-up from standard. It's just that there is a "light duty" version. The "not light" is just that standard stuff.

ok got it its going to be a pretty penny do i need new brake lines? or are they still compatable? forgot to mention that my truck is a 86 silverado...one more question and that will be it hopefully do the milling job on these drop spindled even look safe?? some poor poor milling right there quite dissapointed.

[lolife99]

Also the HD rotor has a different inner bearing.
But I would buy new bearings also.

Since your truck is an '86 I would just get '86 HD calipers, since your brake hoses are probably now attached with a 10mm metric banjo bolt.
The 73-78 calipers have a standard 7/16-20 banjo bolt.

well i would get HD calipers for my year but the guys at autozone and oriellies look dumbfound lol and i dont seem to find HD calipers for my year please send me a link? thanks!

thanks!

[ksbrktracer]

Thank you for posting up that info Keith. We started out ordering spindles for the 1" rotors but then He remeasured and said he had the 1.25" rotor.
Now the thing that hurts is shipping stuff back and I suggested going ahead and switching over to the 1.25 rotors but I think he may have gotten ahold of one of the guys that works at my local Oreillys store. I have to look my own stuff up usually ........ !!!!! Those #s will be a big help for him.

[StarDust]

they sure will! well thanks guys ill be buying the heavy half stuff by tomorrow..

[StarDust]

A little update..i was going to go to buy the heavy half today but then my pops stopped me and refused to let me buy the stuff because of too much work money and risk of not fitting so he basically gave me two options fork over 300+ to buy belltech spindles or call it a loss and sell the spindles i have now and try to resell them...i am in a money pit!

Why don't you just send them back and get the light duty 1" version from the same Vendor???
It was your error on rotor width.

[StarDust]

Yes i know.it was my error thats what i was planning on to just return them and get the correct ones i had told tommy how much would it be but my pops is stubborn i guess i dont even know he wont let me upgrade to heavy half nor ship them back to tommy even though im paying everything....

No matter which way you go ........ Look in your glove box for the spid label and it should have a set of #s that may correspond with the ones Keith posted. see the list below .
