    '65 Skylark Disc Brake Swap

    I started the disc brake swap on my '65 Skylark, when I noticed my rearend axle seal was blown and discovered my rear end was shot (burnt fluid etc). See this thread:


    Anyway here is the progress/findings so far on my '65 Skylark disc brake swap: (Hopefully someone can use this info.)

    Using '72 Monte Carlo spindles, calipers, caliper brackets, rotors.

    The holes that go through the original steering arms to mount the spindles must be enlarged slightly.

    I was originally going leave it as a manual setup, but the brake pedal rod on the original single master cylinder is not removeable. The easiest fix was to buy a 9" booster (where the rod is attached)... And I am using a rebuilt '67 Skylark dual master cylinder. ----or if you still want the manual setup, you are going to have to find a pedal rod from the junkyard.

    I'm using the pre-bent power disc brake swap line kit from InlineTube...

    I have the brake assemblies mounted -- that's as far as I've gotten because I'm waiting for my rearend to be built.

    I will post my progess...

    :TU: Excellent info Dan. Document the **#@%^ out of it and include the rear build up too. Part #'s are real important in my book.
    Thanks for your efforts. :beer

    Ok, the disc swap is now complete... I'm taking some photos and making a list of the parts/modifications... Stay tuned. I will be posting the details of the swap for everyone in the next few days, or after the Buick race this weekend for sure...

    What a difference!

    Picture of "long" power booster rod. This is the long rod that came with the booster... You must find a smaller one. See note from above post.

    Frame Brackets

    I had to enlarge the frame brackets to fit the new flexible rubber hoses. I also added this "spacer thingy" I got from a brake store.
    See pic.

    Can you itemize the cost of the conversion?

    Prices would be great

    I just bought all parts new except the booster,master cylinder, hoses, and prop valve for $575.00. The booster, master with bleed screws, lines to prop valve and metering valve by the master are used from a 70 Monte Carlo. Was this a good deal?
    I plan on running headers and heard the prop valve may be to close.

    425 Dual Quad Restoring 65 'Lark - help

    Looks good, planning doing similar to mine so it's interesting to see where the prop valve goes. Is it supported on the body or supported just by the lines?

    I have an '81 Le Sabre set up to go on. I'll have to live with the plastic master cylinder reservoir.
    Do you think I can use the master cylinder & pedal box complete? To my mind this was the safest way of doing everything.

    best regards & thanks
