I took the CS for its first run last week the car is a full restoration , not registered yet, only drove in my dead end street , when I applied the brakes it felt like one rear wheel locked on .I then went into reverse and it seemed ok then it happened again. I have time now to find the problem ,the brake pedal is just above half, when I start the car the pedal is hard up max ,any ideas what to look for? New booster master cylinder brakes etc

Too soon to say...the car needs a good run with firm brake applications from various speeds to bed in...if it locks or pulls either way...limp home and re-adjust or look for a problem like a blown wheel cylinder (Yes, new ones can blow)

you could try some forward and reverse stops in the street (at your own licence peril!)

In Vic you can get a temporary permit if taking an unregistered car to be registered or repaired or for a roadworthy. You are then covered for TP insurance.

addressing the problem - pull the drum off, there will be something floating around in there, likely rubber - I once had part of the boot from a wheel cylinder come adrift and did exactly what you describe

At the same time, double check that the correct size wheel cylinders are fitted.

Also check they are both correctly adjusted and tyre pressures are what they should be.

And the linings are hooked up the right way round and the drums are true.

Well done finding that mate!!

Take it back to the workshop that did the work...its liable to do the same thing again
