I have a 68 chevelle with manual drum brakes. I have caliper mounting brackets, but need to know what rotors will fit this type of set up. Also, I need to know what booster/master cylinder will work. Thanks

I'm almost positive '68-'72 Chevelles, Montes and Elkys used the same brake stuff.

the story goes like this 67-68 disc stuff is different then 69-72 unless your restoring an orginal car that came with them stay away from the 67-68 discs they are 4 piston calipers & prone to leak unless resleaved also the rotors are harder to get & more expensive... on the bright side 69 -72 stuff is easy to find & cheap !! complete NEW kits run around 900 & a lot less if you find em at junkyard :)

You can find good kits for about $600 if you shop around. Do a search for previous posts on this topic, and you'll find several possible sources. IMO, a kit is the way to go, as you don't really need to know all the part numbers and worry about what fits what etc... everything is right there in the box, ready to bolt on.

Also keep in mind that most 14" wheels will interfere with the calipers, so you might have to step up to 15". This might cost just as much as the brake swap itself, or even more. Don't ask me how I know. ;)

I got mine at swap meet for 650, so yeah shop around well worht the money.

yes your correct there are cheaper kits & I do tend to over budget my projects when planning them.... I hate coming up a couple of bucks short of being able to drive it ... ;) & we all know that there is going to be EXTRA stuff needed !!! shocks,upper & lower control arm bushings, ball joints, bump stops for control arms.... ect ect you know the little stuff ;) & thats not even thinking about the Rims not fitting anymore !!! can I up my budget ????

I am 17 year old on a budget so I will probably won't buy the kit. I just need to upgrade to disk, because I can barely stop with manual drums. Anyone else have that problem too.

I don't want to talk you out of a disc swap, but if you're on a really tight budget you might consider rebuilding your drum brakes until you can afford power disc brakes. The advantages of disc brakes are that they won't fade and don't have to be adjusted to brake evenly. But manual disc brakes require just as much or more pedal pressure than manual drums so IMO, you're not really better off with discs as far as that goes.

If your drums and brake cylinders are in good shape, you could just get the shoes and a hardware kit. Drums can be a decent alternative if they are in good shape and adjusted properly. Still, disc brakes are superior if you can afford them.

I have non power drums all the way around my '69 Nova. It stops ok, but obviously not as good as discs. I'm running a small block in it. Is your car a big block?

My Chevelle has power drum brakes but I am converting over to discs now that I have a big block sitting up front.

The last hot rod I owned was a small blocked S-10.....it had front discs but they were non power and the engine was all cast iron except the intake....it stopped about as good as my Nova does IMO.

Do you think I can do a power disk upgrade for under $400

sure ... learn what A bodys to take the parts off at the junkyard just besure to have someone along thats done this job before .... the springs can be a hazzard to your life limbs & future happness ... & knowing what to messure will keep you from buying things twice like rotor thickness.. some stuff you'll still have to buy new .. like brake hose's & new brake pads ... wouldn't hurt to rebuild calipers the kits are cheap ... as far as that goes rebuilt calipers sometimes come with pads.. like I said get someone who knows what to buy & you can peice togather a power disc setup for 400 dollars might even have cash left over for lunch... 99c burgers anyone ??

I bought a power disc conversion kit from The Right Stuff Detailing. The kit had everything minus all the stuff you might as well replace while it's apart (ball joints etc). It was a very simple bolt on application. The kit cost about $650 and included a 7" dual booster (great if you have a big block), calipers, rotors, spindles, brake hoses, pads, bearings, dual master cylinder, proportioning valve. This was the most complete kit I could find. Don't mess around with swapping drums to discs if you are not upgrading to power. If money is tight you would be better off upgrading to power and keeping the drums so you don't need to stand on the brake pedal to stop.

Like 68KMENO said, it sure can be done but you need to do your homework. You can get a complete, used setup for as little as $200 (or even less) and with a little bit of luck, all the parts will be usable. If needed, you can rebuild calipers and master cylinder for next to nothing, but turning the rotors and rebuilding the booster are things you need to leave to the pros. IMO, the most important thing is that the set is complete when you buy it. It's usually cheaper that way, all those whatnots you need tend to add up.

You better get ready though, once you start inspecting that used set, you'll probably find that you need new bearings, new brake hoses, new this, new that etc. It's almost impossible to determine this before you buy, so it's a bit of a gamble. If you buy a set where everything needs to be replaced or rebuilt, you might even end up spending as much as you would pay for a kit.

Does anybody know if their is another car or another year I can take the brakes off of than the 69-72 A body. Those cars are kind of rare to find in the junk yard, arn't they. Also the rotors need to have the right offset for the calipers. Keep in mind, I am using my stock spindles and I have the bracket.

Here's a couple topics I put together that should answer most of your questions.

If you have original drum spindles and hubs you can re-use these and get a cool
set up with with a new caliper bracket and 12" Vette rotors and calipers
Check it out and good luck
