Great job Mark! We've had this conversation many times, buying a kit that is supposed to be plug and play and you have to do so much fabrication to get it to work. This always bargles my mind how people get things done with just a basic tool kit.

Very true. Nothing is easy if you want it right. Hopefully if someone is considering something like this they will at least know what they are getting into.
Thanks for the video Mark. I can not believe I didn't see this video before I did the exact conversion on my 85 Grand National. I used the kit that Jegs sells....it is 99% identical to t he kit you used. You hit the nail on the head when you said that this is not a true plug and play kit....a few mods were needed...actually almost identical to your mods. My rear axle had to be cleaned up and burred....along with the new longer lug nuts. I went ahead and changed the axle seals and bearings. Your ebrake cable setup was very quick. Mine took almost longer to figure out than the conversion. Thanks again for the video.. Subscribed!!!

Hi Simon, We got the kit from Pirate Jack. Here is a link to their website: piratejack.net/disc-brake-kits/ If you want to make a substitution or have questions give them a call as they are really cool to deal with. We were able to make adjustments to their kit to match what the owner wanted and they worked with us no problem. Most of these kits seem to be made at the same place and sold by a great many dealers so price and customer service is important. Let me know if you need anything else.

It is going to stop really nice. Those drum brakes were barely passable for stopping at moderate speeds.
I actually need to change the size of my studs to M12 to match the new front disc brakes. In your opinion, would I just need an M12 metal drill bit to open up the stud holes? Or do I need to do little by little with a burr tool?
@FoothillPaintandFabrication
5 ай бұрын
Since the studs press in I would use a reamer or drill bit the correct size for the studs. If you have the studs measure the knurled area and go slightly smaller. A 12mm drill bit might be the correct choice but checking the knurled area diameter is a good idea before you buy the bit or reamer. See if there are specs on your studs that show the knurled diameter and hopefully what the hole size should be. Good luck Mark

Why not put it on the lathe, which be completely centered it would take off the material you need without making an oblong or anything it would be completely centered completely balanced and just take off that you can do that on the axle or you could do that on the disc either one it would be in a lathe it be turning straight and clean and just take the material away you need it'll be a nice clean finish and to me that would be the best way to do it

A lathe would be best of course but not many guys have a lathe that can swing an axle. It would require a trip to the machine shop. Most are doing this on a weekend in the garage when machine shops are closed.

My axle hubs have to be turned down because they don't fit in the disc. Then I have to shim the caliper brackets. One bolt is hitting the brake pad. What a headache!
@FoothillPaintandFabrication

Yeah either open up the hole in the disc or take a little off the axle hub. With the burr tool it only took a few minutes to get the discs to fit and only a few thousands removed. Most of the time the caliper bracket needs to be shimmed to align the caliper to the disc so there is enough clearance on the outside pad. I didn't run into any bolt clearance issues. Are you working on an A Body or F Body? Mark

@FoothillPaintandFabrication
Жыл бұрын
They are used to push the caliper bracket out from the rear end tube flange if needed. On some cars the caliper may sit to far inboard causing the pads to bind. Mock up the caliper bracket, temporarily slide the axle in with the rotor on it and the install the caliper with brake pads installed. There should be a small gap to allow the rotor to turn, if not install spacer shims as needed. They will go between the caliper bracket and axle tube flange. Let me know if that answers your question. Mark

Yeah they look good and like a simple upgrade but they really are not. The Eldorado rear caliper is commonly used and packaged with aftermarket caliper sets, even higher end ones because of the emergency brake set up, Definitely not an easy driveway weekend project. As far as having the caliper in the forward position goes it would cause E-brake cable issues, not impossible to overcome but longer cables would be needed for sure. I think on the F body or G body one caliper is on the front of the axle and the other is on the rear. Can't remember which though.
Good thing you had the rear end out to install the caddy brakes, they are a pain to do while on the vehicle, they are also a pain to adjust after a test drive, I have same kit on my C10. Do you have a video on adjusting these caddy brakes for better braking?
@FoothillPaintandFabrication
11 ай бұрын
The only adjustment is by using the parking brake lever on the caliper. Have you tried cycling your parking brake several times? There should be minimal play in the parking brake lever (about 1/16" to 1/8" from its stop when you push it forward by hand) so check that first. I bench adjusted them and didn't do a detail video sorry but there are some out there I am sure. Search for Cadillac Eldorado rear brake caliper adjustment and something should come up. These calipers are used by a bunch of performance/aftermarket manufacturers so one of them must have a video. Mark

New viewer. I have been reviewing YT videos on the rear disc conversion for my 1967 Camaro, and your video came up. I have to say it’s the most comprehensive one I’ve seen on the subject. But I do have a few questions. First, assuming this is a “Right Stuff “ kit, as I saw the part number on the box at the beginning, I think. Looked like their sequence of numbers, but I know Speedway Motors markets it too, and I gathered other do as well. So, is the different color options for the calipers? I didn’t see dust shields, which in other videos, I have. Since I have not actually ordered the kit yet, I have not completely researched the options, although I know they have a separate number for 1968-69 F Bodies with the staggered shock/ staggered caliper arrangement. In any case, thanks for the heads up informative video , so I know what to be on the lookout for. Might even have to convert my Chevelle to rear discs, too! I have gone through your list of videos and clicked “save to watch later” for more educational help! Thumbs up!

Thanks Charlie and welcome to the channel. Yes several people sell these "kits" so shop around for the best deal for you. Pirate Jack is pretty easy to work with if you want to make a substitution. You might want to call them as far as caliber color is concerned. No shields on the back but they are on the front. Not sure how much they would help on the back anyways. The 65 stops so much nicer with these brakes now. Let me know if you have anymore questions. Mark

Mark, did you have to extract the piston at all to properly set the correct pad pressure? I just put mine in and they are slightly wobbly and when I press my brake pedal, I am not getting a full firm pad press. Don't we need to unscrew the piston so that the pads are tight against the rotor? I didn't see this part in your video, but I did see that your piston was quite far out compared to mine. What I heard is that we need to screw the piston out so that the pads just barely won't fit into the rotor. Then screw the piston in just a tiny bit so that the caliper with pads slides on very tight. Is thus correct and how you did it?
@FoothillPaintandFabrication
Жыл бұрын
Mark, from what I understand screwing the piston in or out would be for the initial parking/emergency brake adjustment. The piston should move out and stay close to the rotor after brake pedal press because there is no return spring and it also gives you instant brake response since there is almost zero clearance between the pad and rotor. When you say wobbly, do you mean the rotor, caliper or pads?
@MHTownsend57
Жыл бұрын
@@FoothillPaintandFabrication The pads in mine are wobbly. I got off the phone with LEED Brakes and they said I need to screw out the piston. Mine was recessed to far in and is not set right I guess. When I was watching your video, you actually out the caliper on with the emergency brake level down and slightly started closing the emergency brake level to get it to fit. Maybe you accidently did it right by doing that. My piston stayed deep into the caliper. The little nipple on the back of the pad keeps the piston from spinning so it would seem I locked the piston in place not far enough out. I'm still learning.
