P1020508

This work guide details the upgrading of a HR drum brake front end to a HR disc brake front end. To perform this upgrade the parts you will need are:

* Disc brake stub axles (2, one from each side)

* Disc brake callipers (2, one from each side)

* New disc brake pads (4, 2 for each calliper)

* Solid brake line and flexible brake line from calliper to fitting where the drum brake flexible line ran from (Not completely necessary but less chance of the line getting “pinched” on the road by any of the suspension)

* Brake booster (VH40)

* Copper brake line from booster to master cylinder

* Steel brake line from booster to junction box (Not completely necessary if you carefully bend the current steel one and mount the booster well back like I have)

* Brake master cylinder (to suit disc brakes)

* Rear brake cylinders (disc brake HRs use different cylinders on the rear to the drum brake setup)

* Rear brake shoes (to suit disc brake front end and different rear cylinder pins from new cylinders)
