1970-74 GM X-Body - Nova / Ventura Disc Brake Conversion

DBK7133 - 70-74 X-Body Manual Disc Brake Conversion Kit (Nova / Ventura) - $645.00
This kit is for cars converting to disc brakes that are concerned with stock appearing components. This is the most stock appearing kit on the market. It features the correct bleeder master cylinder, proportioning valve hung off factory bracket at the master cylinder. Once the kit is installed, even the purest will not be able to tell it from factory. The master cylinder lines route the same as the originals, and the correct valve allows you to use the rest of your factory existing lines. This kit has everything you will need for your conversion. This is truly the most complete kit on the market.

Some companies say they have a complete kit but where are the, flex hoses, hard brake lines, vacuum hose, and prop valve? All other kits on the market have you making up your own lines and fabricating pieces just to get the kit to work. NOT ANYMORE. While the other guys leave you hanging with generic parts, we included it all, right down to the plumbing. Here at Inline Tube, we work on our own cars and want the same thing you do - a complete kit with all the pieces that installs in a few hours.


Complete Kit Includes (All New Parts): Spindles with Bearing and Seals, Rotors, Backing Plates, Loaded Calipers with Pads, Caliper Brackets, Bleeder Master Cylinder, Prop. Valve, Prop Valve Mounting Bracket, 2pc Master Cylinder Brake Lines, Brake Hoses with Banjo Bolts & Crush Washers, and Installation Instructions. These are all brand new parts! 

More Details - Our factory style disc brake conversions are based off all factory components. Disc brakes was an option in 1970-74 and if you ordered them this is what they would look like. The master cylinder is the 1968-74 disc brake bleeder master cylinder. The master has the prop. valve off the bracket off the stud of the booster.  The prop valve mounts in the same location as the factory, under the master cylinder and is separated into front and rear. By having this valve in the right location, it allows you to reuse your existing brake lines. The lower wheel kit is 1970-74 X-Body using the improved single piston caliper. The single piston caliper, new for 1969 proved to be a problem free caliper with superior design. All the components are stock, so 20 years from now if you have to replace the brake pads, they will be available.

Some companies use the brass 5 port valve, but this valve is mounted up at the master cylinder on the wrong bracket.  You also have to make all new lines that do not look factory because of the placement of the valve. Other companies supply only the adjustable valve, and since there is no distribution block, there is no way to separate the front system from the rear except to cut up your lines and try to make something work. Most other companies supply smooth boosters and generic master cylinders so the kit price can be reduced. Our kit also uses the correct standard 7/16"-20 caliper, not a late model metric caliper, so when you mount the brake hose it screws right in with no adapter. We also provide the right length brake hose and the frame mounting brackets so your hose will hook up with no washers, adapters or generic parts. Not all disc brakes are the same! With the prices of stock muscle cars at an all time high, the more stock and correct the car is, the higher the return on your investment. 

1967 was the first year for disc brakes and the dual master.  All cars from 1967-69 had a dual master with a distribution block. 1967-69 factory disc brake cars had a distribution block, but it worked in conjunction with a barrel-shaped hold valve that hung off the stud of the master cylinder making this a two part valve on disc brake cars and a single block on drum brake cars. 1967 was also the first year for disc brakes so they used dual piston calipers. 1968 was the last year of the dual piston caliper. 1969-74 all used the improved design single piston caliper. 

All conversions use factory components so they will work with stock 14" wheels.
