[T3] Re/ Brake Hose Bracket etc

[J. Jonik]

Good to know about possible flaps inside brake hoses causing problems.  One thing though:  Is it likely that more than one hose will go flappy inside at the same time?  That is....car pulling to one side or the other during braking ought be a symptom of interior flaps.  Yes? No?

[PS:  This can be part of yet another chapter for a repair manual...by someone...for OLD T-3s.  The regular books don't say nothin' about what to do about rusted, frozen nuts, or electric wire deterioration, about maybe weakened grounds due to rust or corrosion, hardened or rotted rubber, rust in and around axle beams, seized or tight calipers, getting clocks working right, getting clutch adjustment wing-nut loose, using new technology (at the paint shop) to get the color to match 40 year old paint, and...well...we all know the rest. ]

If the hose is wearing internally, sometimes they can form flaps  that act

Basically it's like Matt said above. When you release the brakes  (take 
your foot off the pedal), and you still feel some dragging at low speed,  
that's collapsed hoses. The thing is, if you ignore that drag when the brakes  
are still cold, the next time you use them (once they've warmed up), the drag  
is even more noticeable, because the fluid has expanded in the lines 
building  pressure and keeping the calipers energized. 

In my case, I thought the PO had replaced the master cylinder with the  
wrong one (1 with compensating valves/ports according to Bentley), so I  
swapped it again, only to have the same issue. At this point, only the hoses  
hadn't been replaced, as it now had a new master cylinder, new calipers, and  
new front rotors (they were worn below their limit), so I replaced the hoses,  
and everything was good to go. Lesson learned, that these hoses collapse  
internally. I'd never ran into it before, but then all of my experience prior 
was with domestic vehicles, and those crack externally when they go bad.
