I have a 68 chevelle Malibu that came with drums all around, but I want to convert to front disks. I noticed that all the front disk conversion kits are around $500-600 through conventional magazine adds, which is a bit much so I went to checkers and Autozone to find original parts for cheap. What I found was that 68 Chevelle's didn't come with disk brakes, but 69 did! Will 69 disk brake setups work on a 68 (Master Cylinder, booster, rotors, calipers, pads and spindles)? If they do then I could pick up a disk brake setup for like $200-300. (granted it wouldn't have sloted rotors, but who cares)

How are you going to mount the calipers to the spindle? 67 & 68 were avalible with 4 piston disc brakes.

Didn't 70-72 have single piston calipers? if so, would that be better than the old 4 piston calipers? Could i use 70-72 spindles on a 68?

depends on how orignal you want your car ... 69-72 a body disc setups go for right around 250.00 used ... at the high perf swap meet .. the orginal 67-68 4 piston one's for more..supply & demand .. Ok now I'll open a can of worms.. the four piston ones work better.... but are prone to leaks unless sleeved with s/s liners & the rotors are getting hard to find & are more expencive then the single piston versions.... so if orginal expencive & leak prone is what you want then the 67-68 4 piston calipers are the way to go.. I know of what I'm talking about my car came with them graemlins/thumbsup.gif

Well, what I'm aiming for is a stock front disk brake setup. I want to just order the spindles, rotors, calipers, and pads through a local checkers or autozone like store. But, when I contacted them they told me that 68 didn't come with disk brakes, are they wrong or can I just order 69 parts instead?

The auto parts store you are going to probably does not sell the 67-68 calipers because they are limited demand and prone to warranty returns so they do not offer them. If you use the improved 69-72 single piston calipers you still need to mount them to the spindle. You will need the brackets modify the spindle to mount them and you will need the prop valve to make it all work. The cost difference is that you get THE additional PIECES that will enable you to install and make the brakes work. You can find a junk yard disc set up and then rebuild replace the worn out parts and MAY save a few $$ if you find a good used set up.

In that case, can you use a 69 spindle on a stock 68? I would think that would eliminate the need to modify the brackets to use 69 calipers?

I believe disc spindles should be the same between 68 & 69.

Disc spindles are different from the drum spindles, the upper mounting boss needs to be machined down to mount the disc caliper bracket - I believe the dimension is .610 inch, but I would definitely doublecheck that before using it as gospel..

The caliper brackets and dust shields will not be something you can get at the parts store; if you find a set of used discs at a swapmeet they should come with the disc spindles.

yes the 69-72 spindles will bolt right on no problems. I would sugest you go that route find complete setup in newspaper or online or maybe right here someones got to be trading up to bigger disk setup go to the global west posts & read who's lookin to upgrade & see if they'll sell you theirs... just an idea smile.gif

buy a 72 monte carlo and take every piece of the brake systen off of it and it will fit on to your 68. how do i know this? i just finished doing it.
