I have a complete 70 KH set up... My question is: are the upper and lower ball joints the same as the drum brakes as well as the upper control arm.....Also, who sells a rebuild kit for the calipers? Thx

Are you starting with 9" or 10" drum brakes? Caliper rebuild kits are still available through normal brake parts suppliers.

Too many people who were born on third base actually believe they've hit a triple.

I have currently have 9" drums.

upper are the same...lower bolts are larger thats it

I did this conversion a few years back I drilled the lower ball joint mounting holes to fit the spindle mounting bolts which were bigger but placed in teh same spot. I believe it went from 1/2 to 9/16.

I hope this helps. I recomend rebuilding the calipers because they will surely have buildup in in the pistons.

Hope this is helpful

I opted to get new balljoints instead of drilling the bolt holes out. That area is low on material enough as it is and I didn't have a drill press. I suppose you could do it with a hand drill but with a bit that big.....

I bought the ball joints. The disks ball jounts were actually cheaper than the ones for drum.

I have another thread going about the proportioning valve but no answers yet. Is it the same for disk and drum brakes?

i would imagine so. the prop valve I got from summet. its an inline deveice between the master cylinder rearward line and the rear brakes.

I would have bought the new bj's but I didnt have any cash at the time and as usual did the job on a shoe string and te bjs were good. I beat the po*p out of it and they didnt fall off yet, but yes, not a lot of meat there. Watch out for sticky pisotns on old KH's and thanks again Dan for the tip on the booster rebuild in portland or.

I have got the K-H brakes on both of my early A-bodys and used the adjustable prop valve from Summit on both and works really wellasmatter o fact,my Dart stops as well or better than most of the cars I have owned and is very predictable.The biggest drawback to the K-H setup is the cost of the components.

Drum brakes do no use a proportioning valve, only a simple distribution block. Proportioning valves are used only with disk brakes.

thanks...just checking because I'm doing the drum to disk conversion. I'm all set now

Hey can you post a link for the proportion valve you got from summit?

Does anyone have a link to this company/kits?
