NStarted the week by collecting the front brake shoes from Auto and Industrial Friction in Arlesey, very pleased with their work.  Next, I finished welding the N/S front brake backplate , then made  a bracket which I could attach to a convenient stud and weld to the new backplate to to prevent the bottom half vibrating about.  After that I prepared and primed the new backplate with red oxide.  While that was curing, I refitted the O/S front brake shoes.   Once the primer was fully cured, I applied two coats of silver Hammerite.   Whilst waiting for each coat to dry, I started work on the N/S front brake servo, cleaning off years of filth and corrosion and removing the rusty air intake.  I next removed the brass vacuum inlet pipe, which needed a lot of heat to undo the screws, and loosened the end cap screws two of which needed a fair amount of heat too.  I snapped the head off one of them, which will require a nut welding on the end to remove.
