1970 Impala Disc Conversion
 
Does anyone know of a vehicle that has disc brakes that i could take to put in place of my drum brakes on my 70 impala?

Some 1970 Impalas had disc brakes from the factory ... and

'69-'70 Impala/Caprice stuff will work.

Stock drum-brake wheels may not clear the calipers, so be sure before you bolt them down tight.

Factory B-body disk brakes were rare when these cars were new. Good luck finding a reasonably priced set now. A quick Google search will turn up many aftermarket conversions for this Impala. Later model spindles will NOT work due to the change from rear steer to front steer in the 1971 model year.

'69-'82 Corvette spindles / brakes make a nice swap. Did it on my '65 Impala. Get everything between the upper and lower ball joints, but use the Impala steering arms.

Yes, the bolt spacing of the two bolts where they bolt to the spindles is the same on Corvette and Impla/BelAir/Biscayne (B body).

Hubs?
 
Ok another question. Do the corvette spindles have their own hubs or are the hubs built into the rotor itself? I'm asking this because i would like slip off rotors rather than the other choice.

If you want slip off rotors, You will probably have to find a newer automobile set-up that can work or be made to work or go to a aftermarket co. and just buy new made for your applacation. JMO. Cole

The hub and rotor are not one piece, but the OEM rotor is riveted to the hub. Replacing the rotors requires drilling and punching out the rivets. The replacement rotors do not have to be riveted. They're simply sandwiched between hub and wheel.
So, yeah, they're "slip off" rotors.

I just ordered this (for a parts customer) from Classic Performance Products.

They mention some reconditioned spindles, but they are currently unavailable ... so you need to find some good used spindles from a 65-68 full-size Chevy.

They will be slip off rotors when you are done drilling the rivets out. but they will come together as one. Cole

Next question. I know I have to change prop valve but do i need to change my master cylinder? And i already have power brakes. Also which prop valve should I get, brand whise? If I need to change master which one do i need to get?

Parts is parts
 
You'd be surprised at what's available over the counter at your local parts store. You just need to know what year and model of car to ask for. Many are rebuilt, but some are new.

Suggest looking for a mom and pop parts store that's been around for years in your local area. They may have parts thats been on the shelf for years, but many rebuilders can supply rebuilt parts.

If you don't have one in your area, this store has old farts behind the counter that can help you and they have quality parts as well!

65 to 70 Impala disk brake convertion
 
got the complete break setup from 70 impala gonna put in on my 65, dry fit kooks like everything lines up well. rotors are a little rough and hard to come by, research tells me that rotors from 66-80 vette rear will fit by mounting on outside of hub. only concern is that wheels will be spaced 1/4" further out on each.
geomitry problems?

anybody got input, concerns?
