Thread: Mechanical Calliper Question

try an isuzu dealer

A search of the DBA catalogue tells me 1991 onward models had 18mm rear discs.

Question is did they use drum a handbrake at the wheel or on the rear of the transmission.

Guess I should look under one and see.

Thanks,

Hi all
some BF ford uites have 16mm vented dis 2mm they get away with it.

I found some AL-KO trailer callipers that will accomodate an 18mm disc.

My engineer has given them the nod so I'll pick up a set and start fabbing some brackets, cables and a lever to make it all happen.

I'd be interested in seeing these calipers. When I worked for Al-Ko, the mechanical calipers were to suit 1/2" & 5/8" disc rotors. Even their current website has only these options...
Al-Ko Mech. Calipers

The calliper is designed to fit a 15mm disc but if you back off the adjustment far enough it will stretch to 18.69mm.

I have one fitted and it seems to work fine and allows the disc to rotate freely when off.

I'll try and post up a photo of it fitted.

Fitting was easier than expected. Looks like the cable/lever arrangement will be more difficult than fitting the callipers!

Here you go. The re's about 1mm clearance between the operating pad and the calliper body.

The disc is a 305mm Nissan Patrol ventilated rear.

The car that started with 250mm disc front and 250mm drum rear now has 305mm discs each end so it should stop ok.

What Is ICV rules? Are you building a type of mountain climbing vehicle (Rock hopping)

Kryn,

ICV stands for Individually Constructed Vehicle.

This is used fo either a newly constructed vehicle or a vehicle that is so modified from standard that it is deemed to be a new vehicle and hence must pass almost all current Australian Design Rules. Tough to do.

The vehicle is a 1985 Mitsubishi L300 van that has been cut down into a pick-up and has had the rear of the chassis narrowed by 300mm.

The engine and gearbox have been replaced with a 317KW HSV 6.2litre V8 that sits in the rear tray facing aft. The 6 speed auto sits in front of the engine (toward the front of the vehicle) and is connected to a Nissan Patrol transfer case that feeds the drive power to the rear axle (down beside the engine, using the front wheel drive output) which is a modified Patrol item with 350mm cut off one side to put the diff centre on one side of the car.

Every panel has been altered in some way (glad I purchased a MIG) and the only mecahnical parts left from the opriginal vehicle is some of the front suspension.

Even the dash and wiring have been totally replaced.

This has taken about 6 months @ 35hours per week to do. Almost ready to start it up and drive then I need to finish the bodywork and paint it.

Why do I do it? Cause I can.

I am curious as to why Patrols are still manufactured and sold with a transmission handbrake, yet the authorities will not allow you to use this option on your ICV, (perhaps because the Patrol is a commercial vehicle, although I doubt that the wagons would be classified that way).
For sure you have chosen an excellent axle there, you don't see many blown Patrol diffs.

In all honesty I don't know why they won't accept a Patrol handbrake in anything but a Patrol.

I actually use one in my Range Rover that's fitted with a supercharged Lexus engine and my Engineer (the same one) didn't have a problem, but then Range Rovers came with transbrakes.

Whislt at first it seemed an inconvenience it's actually worked out quite well as I needed to lower the radiator that sat above the trans brake so getting rid of it made room to fit it all together.

I'll try and get a photo or two over the weekend and post it up.

I haven't taken any photos of the build as getting the camera filthy doesn't impress the wife!!!!
