[Healeys] Brake issue

[Kees Oudesluijs]

Go through each component one by one. Start with new brake hoses if they 
are still the old fashioned rubber/textile construction. How old are 
they by the way? Probably decades so renewal was probably well overdue. 
Also flush the entire brake system with fresh brake fluid as there may 
be some debris in it somewhere. Try again and if solved it may well have 
been collapsed inner wall of one or both of the tubes. If not solved 
adjust the rod on the MBC. Still not solved, renew or overhaul the MBC 
and adjust the rod.

When rebuilding brake components do NOT use clean brake fluid but the 
special brake grease from Até, Girling or equivalent.

Overheating is unlikely as that will generally lead to complete loss of 
brakes.
