Rear brake caliper wind up mechanism/handbrake

[Campbeli]

I think your question has given me the answer!
So the piston must need to be wound in, not just pushed in?
So I must need to select the right plate from the brake calliper kit that has lugs that match the face of the piston?
I was trying with a flat plate and that was getting me nowhere.
And both callipers are RH? The kit I bought has a RH and LH tool.

Thanks for the advice!

Off and On topic

Above it was mentioned that the Alfa Sud  inboard front Brake adjusters and Alfetta Rear Inboard brake adjusters dont self adjust .
I had this problem in the mid 80s and found a solution.
If the calipers are in good usable working condition,there is a cure.
Did it to all my customers cars that mentioned the problem.
All were extremely happy with the result.
Only time they needed adjusting was when the brake pads were changed.
And yes,,adjusted when new pads fitted,,but never in between
The ONLY unhappy people were the ones who did not believe me and said there is no cure and could not be done.

I used to laugh at the time,,that some Alfa owners paid $1000 for a reconditioned pair of calipers that was guaranteed to self adjust.They did not.

So,,to my good friend Cool Jesus,,,you can do it the easy way and use your original inboard rear calipers on your Alfetta,,or change and re-engineer the handbrake system with the 147 system you mentioned.

Hi Campbeli

The way I do it

Slacken handbrake cable from handbrake lever so the handbrake cables can be removed from calipers.
Remove caliper,,but NOT hydraulic hose.
Unscrew fluid cap at reservoir and remove some fluid,,as winding in the caliper piston will raise the reservoir fluid level.
I mount the caliper the the suspension strut via a nut and bolt i keep in the kit.
The reason for this is so i have an extra hand to wind the caliper piston in and adjust the tool while winding the piston in clockwise.
Hopefully you will find the hole tab in the strut to secure the caliper via 1 caliper mount.
PM me if you dont understand and will explain ot over the phone.

Good advice, thanks QV! I'll have another crack at it. Might need to call for some 105 parts soon anyway.

Pads and discs in less the 10 min! So easy?

Making good progress (I think), thanks to all the good advice.
New pads are in and slid pins re-greased.
The RHS top pin was stuck, which explains the uneven pad wear.

Can anyone tell me why the top pin has a thicker section than the bottom pin and does not move in and out as easily? The thicker pin was the one that had seized.

New pads are rubbing on the disc  (not due to handbrake) so I guess that will resolve itself during the bedding in period.
