[TR] [6pack] Master Cylinder Rebuild

[Robert Rochlin]

Hi Richard,
	I sent my m/c off to a reputable (I thought ) rebuilder for a complete rebuild and installed it back installed it in the TR6.  As I recall it worked fine for a short time and then on day I was puling out of the garage and the brakes totally failed.  The TR6 rolled int my P/U truck dented the door, and pushed in the front o the Tr6 hood. A very expensive afternoon. I sent the m/c back to the rebuilder as I had time to kill while the body shop fixed the TR6.  They rebuilt the m/c again gratis and I reinstalled it.  After about 8 months the m/c started to fail again, but slowly… I replaced it with a new Girling and it has gone several seasons working fine but now I’m getting the slow sinking pedal. Before replacing it again I am going to replace the seals myself.
	  Although I’ve had good luck with several rebuilt components including starters, carburetors, shocks, and distributers,  I’ll never send a master cylinder to a rebuilder again.
	Best,
	Bob

I don't wish to directly name and disparage the vendor since they are always quite willing to make things right, but their name does grow on the 'north side of the tree'. The question I ponder and why I am writing is to ask is: How did your M/Cs fail?

>         I’ve had a checkered history with master cylinders. In the past I’ve sent m/c off to be rebuilt by reputable rebuilders only to have them catastrophically fail soon after reinstallation.  I’m figuring that I can improve on that record.  When I went to the Buckeye Triumph site to review the rebuild process the article recommended red grease.  I don’t have any, but I do have Volvo silicone breaks grease.  In the absence of red brake grease can I just apply brake fluid as lubricant to do the rebuild or should i bite the bullet and get the red brake grease.  About the only red grease I could fine was on Amazon and it was pretty pricey, $16.00 plus $8.00 shipping.
