DISC BRAKE KITS / SERIES II, IIA, III 1960 ON
Front Kit shown PLA6100KV
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
