Talking 1965 Impala Budget Disc Brake Conversion

I have a 1965 Impala SS, it has drum brakes all the way around. I want to know the cheapest way to get disc brakes on it. I was thinking of going to the junk yard and taking the off a newer B-Body like a caprice or something. Would that work? Or What are some other suggestions? I'm hopping to get at least 2 piston brakes in the front, the 1 piston kits seem to small for such a large and heavy car.

Some 1967-1970 Impala's had factory disc brakes. They are a direct bolt on for 1965-1966 Impala's. You can use Corvette rotors instead of the original ones. You have to use the disc brake spindles.

Would it be possible to use some from maybe a 93 Roadmaster, I see Roadmasters at the junk yards all the time and I know it's also on the B-Body like the Impala but I'm not sure if it will fit

I was hopping those would work. So the front disc brakes would fit if I took them off and early model Iroc?

BTW What car can I get the rear disc brakes from?

I'm not so sure the camaro disc brakes will fit with out some kind of adapter. The ball joints and spindle are wrong. The aftermarket kits use the smaller car disc brake setup.

I also heard that anywhere from 1965 to somewhere around 1980 corvette parts will work too?

Disc brake conversions......

Hi guys,I have a '66 Pontiac B body (Strato-Chief 2 dr Post car) and I successfuly installed '65-'81 Corvette brakes(4 piston calipers) on all 4 corners.This car stops just as good as my '11 Ram. Easy to do.The fronts are complete C3 from spindle to hub to rotor.For those interested,the rears are a little bit of work but very much do able.

Hey Rebelrouser, would you happen to know if the 4 piston set up would work with the A-Body and F-Body cars?

BTW for the install to work on the B-Body what parts are needed? Does anything need to be modified or is it just all direct bolt on?

For A and F body that would be alot of research regarding the fronts.For the rears,the mounting flange has a smaller bolt pattern for the caliper mounting brackets.GM used B body axle tubes to put the 4 piston brakes on the rear's of the Camaro('69).For '65-'68 B body,the fronts are Corvette.Now the rears-first thing is that the rears are '65-'81 Corvette brakes and the other thing to remember is that everything is right hand side x2.No left hand parts on the rear brakes.2 right rear caliper mounting brackets,a pair of JL8 e-brake cables(ebay),2 right hand rear dust/splash shields(Corvette),a pair of e brake cable mounting brakets(JL8 brakes.com).When purchasing the emergency brake kit,you'll have to get another right hand e brake cable actuator/lever(2 pieces).There will be some minor welding required and some grinding/turning of the axle flanges.This is required to push the axles inside of the rear brake shoes to re-install the c-clips.The e brake cables on the right pull from the front of the diff as the left side pulls from the rear.You'll see when you notice the difference in cable lengths.The short one goes on the right,the longer one goes to the left under and to the back side of the braking system.And to make this come together under the car,both cable connectors will have to be lenghtened by approx. 2 in. or so.It's a real simple process with a little patience but the end result is well worth it.Don't forget to change the proportioning valve to disc/disc.Up here in Calgary(Canada) I found a good used front brake set up for $500(needed rotors,calipers,dust shields).The rears I bought all new.No used there.The rear calipers sit at about 11 o'clock and 1 o'clock on the diff when mounted so be careful when choosing a wheel to go up under.I choose the Torque Thrust(15x7) 'cause those wheels were designed for the Corvette's braking system in '65 to clear the big brake calipers and I wanted to keep the '60's looking theme.It all could be done in a weekend or two maximum.It took me 4 months two winters ago as there was alot of trial and error-lots of pre-fitting,on and off stuff.Oh,and one more note,on the left side of the diff where the shock mount is there is a hole just above the shock bolt.Open that hole up(step drill bit) so to run the emergency cable through up to the braking system.This system is adaptable to 10 or 12 bolt "B" diffs.If in doubt about what pieces are needed,look up JL8 for the some guidance.This system is how GM did it on the '69 Camaro.Again,do some research as it will pay off!

You asked about "A" and "F" body.In what regards would it be pertaining to? The fronts or the rears? "A" body cars never had rear disc and "F" body only in '69 and again in '79(Firebirds).I have an April '69 12 bolt "F" body rear disc brake diff I'm somewhat restoring-getting back to useable condition.

Let me know how you made out or if you have any problems/questions.

Good luck and enjoy when finished,

I've seen those kits before. I don't like them too much because they're quite small and they're only single piston. I'm really interested in learning more about about the 4 Wheel, 4 Pistons Corvette conversion.

Yeah, I've seen those on ebay too. They're quite expensive the the kit.

What brand are you using for you 66? How much did you pay for the whole kit?
