front brake upgrade: semi-huck to duo-servo

[Blacky]

Today is brake day - first problem the new slave cylinders don’t fit the same as the originals so had to take the die grinder to the freshly powder coated backing plates

Don’t like the look of this one bit - look at the angle the pushrods are on


Bit different to the old brakes -

Way too much thread showing on the adjuster at the bottom too, indicating they should be sitting quite a bit further away from the top pivot pin. I’ve got some original bits here I can photograph somewhere, albeit balljoint front and wider commercial rear. I think the rears may have been modified to fit disc front compatible rear wheel cylinders.

Ahh, but you haven’t got the drums on yet?

Correct - adjusters weren’t adjusted, wound them in to fit the drums
Also noticed after taking that pic that I had fitted the shoes arse about on the left side


Fixed, then installed the drivers side and found the new slave cylinders have a different thread to the FB style slaves


New brake lines and tie rod ends tomorrow and hopefully that will be job done

Drivers side done, passenger side is coming for a ride down the hill tomorrow as a sample for the new brake lines

It does make me laugh, those $120 dollar slave cylinders looking pretty good about now !
The hoses are a bugger as well.

I reckon it will be worth it. Even better with the wider HD kingpin ones.

I tried to find HD kingpin stuff but its unobtanium , don't know how you would go buying new drums or other bits either ......

They don’t make the wider drums it seems so yes.

Wasn't sure if the drums would interchange with the HR and onwards drums - a master parts cattledog might clear it up but it's all academic anyway

I think the KTG drums are bigger diameter and Torana are different offset. FB to EH and HD HR rear get a gurnsey. Poor old HD HR front miss out.

The ball joint ones are different mate, they are not interchangable

[Errol62]

The drums and shoes will be the same, different backing plates and steering knuckle of course.
