Now you can install the latest Defender disc brake components onto your trusty 88” or 109” Land Rover and enjoy amazingly quick and controlled stopping power. Front kits are based on a new hub
assembly and new swivel ball housing, cast from ductile iron with a minimum strength rating of 80,000 pounds per square inch, this kit is an engineering masterpiece. The front caliper mounts are cast into the housings, just like Defender, to handle the massive 4 piston Defender calipers that grab 12 inch vented Defender discs, just like the NAS 90 enjoys. Timm’s rear conversion kit uses the same hub assemblies with solid Defender rear discs and 2 piston Defender rear calipers. Using all Defender brake components, as well as wheel bearings and seals, means easy service, easy parts availability in the future, and adds directly to the value of your Land Rover.

These kits are designed to work with an 88” or 109” dual power master cylinder available on Land Rovers manufactured from 1969 through 1984. For owners with early single non-power system master cylinders, you will need to convert to a dual power master cylinder. This conversion involves installing a vacuum port into your intake manifold, installing a dual power pedal box assembly which houses the dual master cylinder, vacuum servo unit and brake light switch. This pedal assembly is larger in size. It will require modifying your wing top, splashguard mount, and installing a Series III style splashguard. You will then need to re-plumb your clutch master, and install additional brake lines to complete the dual circuit.

You will also have the option of adding in a safety failure junction valve, with or without warning light, and choosing between hydraulically or mechanically activated brake lights. These parts can be found in our catalog or on our website in our Series III brake section. We also have available a good selection of second hand dual pedal box assemblies.
