Well my buddy is planning on going to BBP disc brakes on his 65 valiant and i was told all you need is the upper control arm, spindle, dust shield, and proportioning valve, and to buy calipers and rotors new. Is this all he really will need? Oh and he will need the BBP rims but he has that covered.

Thanks, Chris.

Master cylinder?

Wow i completely forgot about that one, will the dual resivor master cylinder bolt up directly in place of the single?

78 volare front brake hoses(they have a metal bracket in the middle of the hose) & I'd cut half of it off & leave the part encircling the hose, you'll see when you get it. get a pair of the "original" hose to caliper ribbed washers from MP.(dont have the # handy). 76 A body & MAYBE all the F bodies have a 5/32" larger bore dia caliper than the 73-75 A bodies which puts more bias towards the front which is a good thing so ask for them. I'd use a 73-76 A body proportioning valve(a new one or possible take apart & clean a used one if that can be done?) or better yet an M body one which gives better proportioning(in this case)& if you are changing your rear brake line add an adj prop valve in the rear to fine tune your proportioning later if needed. Get an alum MC of the correct dia(probably 15/16" or 7/8" but Doctor Diff will have the final say on that) & use an alum adapter to better cover the firewall hole. I'd mount the calipers to the front(if no sway bar) and measure the fit of your intended wheels/tires/offset CAREFULLY before you purchase them and some better quality(than stock) pads.

Wow lots of info there, So you are saying the 76 A body calipers will work with a 73-75 spindle? im not sure exactly what year the car is but its a BBP disc slant6 car and he doesnt want to run drums. Ill have him read over this too just so there are two minds comprehending this one, Also he is going to need to run new back brake lines since there is a narrowed D60 under the car and no brakes hooked up to it. Thanks, Chris.

Doctor Diff has some tapered bushings that will allow the use of the original '65 upper control arm.

Well we went today and got the upper control arm, spindle and some other odds and ends but the proportioning valve, calipers, and rotors were all gone but he planned on getting all those new. And he went and got new front end bushings. Thanks for all the help.
