The Mafac centerpull brakes need to be paired with Mafac levers because of long cable draw.

Got them pics of the rusty crusty 70's #Peugeot #bicycle. Got the back wheel off and managed to get the chain to move off the cranks to test the bb (it spins its just gritty). The freewheel spins good. The rear axle does not. The simplex is cracked where the limit screw is (plastic). 1/2

oh yeah absolutely - I saw that Kool-Stop even do replacement pads for the original Mafac holders! Definitely getting some of those, the brakes are not exactly confidence-inspiring right now

"Cold setting" WAS an art form!
However, there was a centerpull brake that allowed toe-in adjustments.
Between the sounds of the steel pie plate spoke guard, serrated rims and the Mafac "squawk," everyone knew who was riding a UO-8.

I used a wrench sized smaller than the bolt, then ground its jaw opening to just fit. The key was to leave the edges square, without any radius. There is so little material at the edges of that Mafac bolt for a normal wrench to have any purchase.

Sometimes a modified tool is best. #BR
Mafac centerpull hangers have notoriously thin-headed bolts. Normal wrenches with radiused edges would slip off.
I ground a small open-end wrench to have a very snug fit on the Mafac 9mm bolt head, as well as leaving the edges of the wrench jaw square.

It's OK to make custom tools for yourself. Off-the-shelf wrenches are often finished with radiused edges and chrome plating, making them slip off thin hardware like that found on Mafac brakes. Invest in an extra tool to modify--it will wind up being a keeper! #BR
