    I searched the forum and found lots of threads on drum to disc brake conversions. My GS350 has front disc and rear drum manual brakes and I want to convert to power brakes. While doing this I plan on replacing the brake lines and upgrading/replacing front suspension components. What parts are needed for the brake conversion? Power Booster, master cylinder, Proportioning valve, Vacuum?? Can I use the rest of the exisitng components? Are there any kits for the conversion or stainless brake line kits you would recommend? Any other suggestions would be greatly appreciated.

    I think all you will need is the booster and the lines from the master cylinder to the proportioning valve. You will use the same master and only have to move the brake rod down to the second hole since you already have front discs.

    Thanks Greg for the reply. Booster, new brake lines, reuse the proportioning valve and master cylinder is all that is needed.
