67 vs 69 brakes

Can anyone tell me if 69 calipers will replace 67 calipers as long as I change the rotors?

It's not a Rotor thingy.

The Caliper Mounting Brackets (as are the backing plates to clear them) are different for 4-piston vs. Single-piston units.

Other V8 things - some of which float
Other V6 things - none of which float
Oh yeah, and 1 "Straight-Six" ...

If a man says something in the garage - and his wife can't hear him - is he still wrong !!!

What he said^
As a matter of fact I've run the rotors from a 68 4 piston set up on my 69 with single piston calipers with no problem.
The Single piston calipers float on their mounting bolts, the four piston calipers mount solid.

Re: 67 vs 69 brakes

So what would I need to do to convert my 4 piston caliper to a single piston caliper?

What you really need is the proper mounting bracket(s) for the caliper you want to use

You can use your present 4-piston Spindles and just change the Mounting Bracket to the Single-piston type.
GM part number for the "Knuckle" is even listed as the same from 1967~69 - Group 6.020 #3966151 ...

You can also use a standard set of Drum Brake spindles if you want to - just mill/trim the upper mount boss down the required amount to allow the caliper mount bracket to sit flat a VIOLA, you have a 'Disc' spindle

So - technically - you only need to have the correct set of Caliper Mounting Brackets for the type of caliper you want to use and you can use (or modify) any of the stock spindles to fit that set-up

Re: 67 vs 69 brakes

Welllll, floating caliper brackets, floating calipers AND floating caliper splash shields.

I just happen to have moved up to JL8 front brakes and have my old floating brackets, calipers and splash shields.

2 Drilled rotor/hubs too.

PM me if you are interested.

Yeah, I understated it a bit. Point being that you need either a donor car or all the left over pieces from a 69 disc brake car.

Got it Lynn - sorry if you took that as a jab, it wasn't.
Just wanted him to know the interchangeability of the original GM stuff

Re: 67 vs 69 brakes

Guys, thanks for the info! I took my rotors and plate off after reading your post and saw the bracket your referring to. I thought the bracket was actually part of the spindle and that's what was throwing me off. I actually found the brackets I need in NPD catalog too. Thanks for the help!

Re: 67 vs 69 brakes

Not trying to hijack a thread here but I'm going through similar situation. An want to make sure I understand. I would like to explain my situation. I went to repack my front bearings on my 67 an to replace my flex lines. I noticed my flex lines I ordered take clips at both ends. the ones I removed was bolted to the caliper. So I call the company I ordered my stainless flex lines from an the tech said it sounds like some one put 69 calipers on my 67. By the way my 67 came with factory power disc brakes on front. An told me in order to do that you must change back plate, mounting bracket, spindle, and rotor cost bought 650 to do that. Well I decided to just get 69 brake lines an when I went to get new bearings the 69 bearings where different than what came out (size) crossed the number over from the ones i had an they where 67 camaro bearings. So now I don't know what I have. Any help would be appreciated O an the number on my current calipers are Delco-moraine 5473497

Re: 67 vs 69 brakes

Front wheel bearings were the same for 67-69 whether disc or drum brakes, so that's a bit odd.

Can you post a picture of your front brakes?

Re: 67 vs 69 brakes

Well that's what I thought. Of course I was at Oreilly getting those an the guy waiting on me was not the sharpest tool in the shed either. So I had him cross the numbers an got tha taken care of. But a. Curious since the tech at right stuff said you have to change everything. An I need to replace my rotors so I don't know if I need to order 67 or 69 rotors.
