Questions and Answers
Don K. on -- Asked:

Irving H. on -- Asked:
Hey what year, make, and model do i need to get replacemeng pads for this conversion. Everything works great just time for new pads
73-87 Chevy 3/4 ton 4x4 front pads for our standard non parking brake calipers
Dusty B. on -- Asked:
What proportioning valve is recommended for this kit?
We recommend the manual adjusting proportioning valve made by Wilwood. Choose the appropriate one for your brake line diameter and I recommend flaring it off the master cylinder so it is up away from water to decrease the chance of it seizing
Andrew G. on -- Asked:
Do the 76-77 Cadallic El Dorado calipers work fine with the K20 rotors?
Todd T. on -- Asked:
Do you know if your parking brake caliper will fit on a 1999+ 14 bolt axle that originally had disc brakes? Previous owner installed axle into Jeep LJ without factory GM e-brake.
No it will not bolt up to the factory mounts
Jordan E. on -- Asked:
does this come with ebrake or as an option? also does this use a standard rotor and pads or is it custom... how large is the rotor as compared to the stock drums...
We currently do not have a parking brake option. We are working on having some made. You can use rear Cadillac Eldorado calipers from 1976-78 with our brackets if you can find them.
This kit uses rotors, pads and calipers off the front of 70's-late 80's K20 4x4 trucks, so they are easy to find at local autoparts stores.
The rotors are 12.5" diameter.
COTY M. on -- Asked:

Nicholas C. on -- Asked:
Will the 14 bolt disc brake conversion work on a 75 Scout D44 ?
No, this kit only works on full float 14 bolt axles and Full float Eaton axles
Wayne on -- Asked:
I have a 72 Chevy 14 bolt do you guys make a disk brake conversion kit for that year? I seen your kit is for 73+ just wondering what is different thanks
It will work on the 72 14 bolt as well. Think our website guy thought they started in 73 as this was the Eaton axle replacement that which last used in 72. The brackets supplied with this kit fit both the Eaton axle and 14 bolt single rear wheel axles.
Miguel S. on -- Asked:
Does this kit fit a 1972 C20 with the 14 bolt 3/4 rear end? Would I just have to buy the el dorado calipers for a parking brake and is that plug and play?
As long as it is the 8 lug full float 14 bolt it will. 1976-77 El Dorado Calipers are what you need to retain the parking brake. Only other thing I would recommend is an adjustable brake proportioning valve in line to the rear brakes.
That 1972 rear end may be the Eaton rear axle though. They fazed out the Eaton rear end in the early 70's for the 14 bolt. I would just confirm which it is as we have kits for both axles.
Tim K. on -- Asked:
Hey guys, will this kit work on an '85 K2500 with a 9.5" Semi-Float 8 Lug 14 bolt rear end? Having trouble finding a kit...
No the wms is different from the full float. A weld on kit may work but we would need to check some measurements on your axle to make sure the bracket can be welded to an adequate spot on the tube
RAY E. on -- Asked:
will this convert 1998 gmc k2500 surburban from drum to disk brakes, doesn't such a conversion require new master cylinder for brakes does this include parking brake,
We don't have anything for that year axle, our kits are for the 87 and older. Depending on how much fluid your master and booster can handle you may be able to stick with stock. Currently our kits do not have parking brake but we are planning on some in the future
Nick T. on -- Asked:
Do these have a provision for a parking brake? I can't really tell for sure in the pictures but it doesn't look like it does.
Our kits currently do not have a parking brake option. 1976-77 Cadillac El Dorado rear calipers will bolt to our brackets and have a parking brake.
