[Mgs] Master cylinder - size of ports -1600 MKII

[Pat Harris - "sammler"]

Paul,

Your mention of the brake light switch, even though on the A it's 
hydraulic and not mechanical, has pointed out to me an easy to reach 
place where I can release the pressure in the system without having to 
get under the car.  Unscrewing it will allow me to check to see if the 
calipers will release.  I'll do that later this morning - after it gets 
a bit warmer than the present 36 degrees - brrrr!

"Blocked port" aspect.  When the piston in the master cylinder is in its 
correct "at rest position" is the only pathway for fluid to return to 
the master cylinder via this small port?  If so should pushing the 
caliper piston back into the caliper cause the brake fluid to move into 
the master cylinder via this pathway?  If so, would this then be an 
indication that the small port was not blocked?

Thanks,
Pat



Thanks,
Pat
