After repeated usage? GW and BamBam are at the top of Black Bear and only one is going down, which one are you taking and why? |

Can we all agree to disagree haha even though this is the disc brake conversion thread. I guess everybody would agree with me that a 67 charger that weighs 4000 lbs with a Big Block in it that can get up to 140 mph should have disc brakes right?????? Well my Charger doesn't and I wish it did! Drums no matter what, are no fun at the end of a drag strip at 100 mph grabbing here and there. Yes they are adjusted well, its just the nature of the beast and the power "one finger" steering Chrysler used in the 60s. Yes this is off topic sorry.

I believe disc brakes are better, and more importantly work way better even when they need to be replaced. I hope my previous comments do not imply differently.
I just feel that fully functional 9" brakes are safe, and are enough nothing more. Worn out brakes whether they are disc or drum, 9" or 11" is another opinion. Edited by jpet - 17 Aug. 2018 at 5:23pm |

Did someone say they figured out an airbag conversion?
Like I said, in my case (and only in my case), I knew the 9's needed work and wanting the wife to drive so I can selfishly look around more, I decided to start looking and while spending money wanted to keep it original looking and mostly feeling yet get something a little better. I figured I would be throwing at least $100 at pads, replacing wheel cylinders, turning, etc, if no major issues like replacing a drum, so I figured I was half way there, I might as well try the disc and get a better pedal feel for the wife. Hopefully, I will accomplished that. But this is just for me. Hoping to get everything done and motor broken in so we can make the FCT and meets some of you guys in person. This site has been very, very helpful and full of friendly and knowledgable guys who are willing to share without the ugliness I've seen in other forums.

Sorry for kicking off the kerfuffle.
And especially sorry for sidetracking this excellent thread with tech info for those interested in doing the disc brake conversion on their jeep.

I'm going to swap out my MB's stock front drums for disc brakes. In my case it's because I like to pull a camper trailer. I was hoping to do it before FCT but don't think it will happen.

Isn't anyone going to mention the reduced unsprung weight and rotating mass and accompanying performance improvement of a disc conversion? (Just throwing it out there for the sake of conversation)

So I'm looking at all this...question for those who have actually done this successfully. What has to be "ground off"? If I use a wheel spacer, so I still have to grind anything? I will be using new wheels, 15" cj5 style. Any idea if this will be a problem? The brake line connection at the hub, does it have to be relocated to make room for the rotor? BTW... for me, being able to stop is really important.... 🙄

Just to clarify, since you are mentioning grinding, we are assuming you are talking about the Chevy disc conversion and not the Geo conversion?

Yes, I am interested in using the stock master cylinder if possible (brand new)...and being able to change back to the original configuration down the road if necessary...

The stock master really is not directly related to the brake conversion, other than it is recommended to get the safety and the correct purportioning valve. Thus thread has basically been talking about 2 different disc conversions. One uses Chevy parts and requires grinding of the knuckles and the Geo Tracker which does not. But there are some very different pro/cons of each. So which are you talking about?

From what I have read on the original posts, the Chevy conversion using the half ton '70's brake system requires something to be ground down. I'm looking for what has to be modified and why. What doesn't fit, and what is keeping it from fitting. If it is the wheel, will wheel spacers correct the issue.

If you go to page four on this thread you can see somebody had to grind at least the knuckle seal down for the caliper.

I've seen pics that show the flange on the knuckle has to be ground so the floating caliper can slide across the flange. I seriously dislike single-piston floating calipers. The points on which they float rust and then they don't float and you only get braking on one side of the disc.

Good into here for front discs !
Question: Is there a photo showing the difference in caliper size between the two ? Not knowing, I am thinking the 'tracker' caliper to be smaller than the GM, but puts out satisfactory piston force. |
