So John (or anyone else) did you ever get this question answered? I'm looking to update my brakes on my 71 Chevelle, and the kits offer 9" or 11" power boosters but I'm not sure which is better or if it matters. I currently have manual drums all around. Thanks

Re: Disc Brake Conversion basics

On my 67 previously drum drum car I have in place a 71 power disc brake MC with 71 calipers and rotors on the front. On the rear I have 01 S10 blazer rear disc using 4x4 caliper mounts and 2wd rotors. Here is my issue when I hit the brakes the fronts work fine and will free wheel once the pedal is released, but the rears hold and it takes more then I think to turn the wheels. My quesion is, is there some kind of residual preasure valve to the rear circuit I keep seeing that they have a 10# ? I am using all the original hard lines and distribution block for drum/drum except for the lines for the rear brakes, there I have the hard lines and rubber hoses from the Blazer. This kinda sucks because all the lines mated up so nice. Any suggestions would be appreciated. I read that an 82 Vette disc disc MC might help?

Re: Disc Brake Conversion basics

Ok so here is one question I hope to get some help with. Back in the day I converted my 66 SS to front disks by using the spindles off a '70s Nova. After the install I had to start using a low profile tire on the front because of tire rub issues. My question/ backstory is if I read this thread right the Nova spindles fall under the 'tall' spindles and thus made my track width wider and put my front tires closer to the fender lip. In the time I was driving the car I had rebuilt the control arms and also put new factory springs in (Moog) and I still had to run the low profiles up front. So I guess what I am trying to ask is if I were to switch to an A body spindle I should be ok to run the same tire all around right? Thanks for any help I'm more of a body guy than suspension/ tire guy. I am trying to get it back together for my wedding in a couple months. It's not going to be completely done but drivable and safe is my goal, the thing has been apart for 7 years and customers cars has always put this one on the back burner, now I have cleared my schedule so I can concentrate on this one car and so far I have got plenty done, anyway I'll shut up. Thanks again for any and all replies!!

I'm having the same issue with my '66 Impala. I want to keep my 14" stock wheels and "SS" hub caps while adding disc brakes in the front. I have found this solution but have no tried it out yet.

disc brake conversion problem
I converted front disc brakes from summit and used the adjustable prop valve everything worked ok with a lot of tweaking but I did not like the set up or the looks so I opted for a combo prop valve pv2 fixed and removed the adjustable and the dist block and the brakes worked fine on 2 test drives well today after setting up for 2 moths went on a short trip and before I even got a block away I could feel the drag on the front brakes I turned around and headed back and the car would nose dive when I pulled back in garage I could smell the brakes I touched front rims and the were very hot what gives what am I missing everything is new any thoughts

Re: Disc Brake Conversion basics

easiest to check for would be a stuck caliper piston. Just remove the caliper and try to push the piston in with a c-clamp - it should go in with only a little force, if it seems sticky there may be some rust on it. Second would be the piston in the MC sticking, but that requires a little more dissassembly to test. Do that one last!

Also when the caliper is off try spinning the wheel to make sure its not a bearing issue.

Re: Disc Brake Conversion basics

I am wondering if anybody has this answer.
I have a 69 Chevelle Malibu that I would like to add a power brake booster to. It has the dual reservoir master cyl with Wilwood front disc. So my question; Is there a booster from any year that will bolt on & avoid going aftermarket?

That one will work and include everything you need, presuming you don't break anything during the install.

I had to replace my dust boots, as I ruined them when I used the pickle fork to split the spindles from the ball joints.

Re: Disc Brake Conversion basics

I have a 1969 SS396 El Camino with factory disc front brakes and factory 14'' SS wheels. I would like to replace all the disc brake components with an all inclusive kit like described in the above post link, or the Wildwood 140-10996 rotor/caliper kit. Nearly all of the kits state they fit with most 15'' wheels. Wil my 14'' factory disc SS whells work with these kits? I really don't want to change tires and wheels. Thanx in advance for helpful info.

Re: Disc Brake Conversion basics

I will add, it is anything but BASIC.

It is advanced and a real PITA. So you either have someone
else to do it for you and pay big bucks or DIY and suffer.

To add to the confusion from what I've learned on my 1969 Chevelle
conversion (which had factory front discs).

When upgrading to 4 wheel disc brakes:
  1. You have to change the proportioning valve for 4 wheel discs.
    1. Get the all brass proportioning valve
  2. You have to remove the hold off valve attached to the Booster.
    1. Appears that you have to get some type of 90 degree adapter
      that is the opposite of a nipple. Name of fitting???

Go with the biggest rotor caliper combination that will fit.
If you don't, you'll be replacing your pads all the time.

Case in point, growing up my folks bought a Country Squire station wagon.
If I recall correctly because the front discs were so small (not really)
but still we had to do a front brake job something like every 9 months. It just ate brakes. Oh, and went through a lot of alternators and one transmission in 5 years.

Hope this helps someone. When I get some part numbers and figures
I can post them here.

Thanks,

Spike

Re: Disc Brake Conversion basics

Im a little confused. I have done this swap on other cars in the past so Im familiar with the process. Ive read the threads on converting a 66 from drum to disc and Im not sure just yet what to figure on doing.
Im going with some aftermarket kit (don't know which yet). Some kits say that changing the spindle isn't necessary while other do and some kits include the spindle. My main concern is do I change the spindle---if so, which way to go to minimize alignment issues.
Im really not interested in a 2" drop--but if its necessary because of steering issues, I could do that. Does anyone have suggestions on an aftermarket supplier?
My end goal is front disc brakes and retain as much of a stock appearance and operation as possible. Thanks for any help guys,,,,
