Brake Servo Cylinder Stop Pin needed

[Basil]

I am missing one tiny little part for my EType brake Booster Servo cylinder. It is a small stop pin that limits the movement of the piston in the bore.

I posted an ad in the Classifieds:

Brake Servo Cyl Stop Pin Needed

Not an easy one to find, ol boy! Good luck.

In the dark recesses of my pea brane there's a passing thought... needle bearing (like from a transmission layshaft)?

I'd be finding something close in diameter and make a mock-up then head to a bearing house. IIRC those pins were hardened so a needle bearing of correct diameter would work as a replacement. Length would be a lesser issue, longer than needed can be ground off.

...just a thought.

 

[Basil]

That will be a last resort. But I'd rather have the real deal if at all possible.

 

[DrEntropy]

Agree. But if one doesn't show up, it ain't likely to be a point loser.

Hydroboost is good folks.
They do NOT do credit cards, which makes it a bummer.

I had my PBR booster rebuilt there.

There is a guy over on jaglovers offering to make you one outta stainless.

There's a booster for CAB's?? Leave it to you Doc to have one or even know that! :laugh:

 

[Silverghost]

Basil, there's a couple of local sources here I can ask....I'll let you know what I find.

Looks like the folks on jaglovers have you set for a stainless pin.

One of their members is making me one and it should be in the mail now.

Just keep in mind stainless is usually SOFT.

...just sayin'...

These pics are pretty short so I don't think that will be an issue and they don't really carry a huge load.

 

[Exotexs]

stainless steel soft? first time I hear that. I use stainless steel bolts, screws, washers, and lockwashers in both my Jags, and those are excrutiantingly hard!

 

[DrEntropy]

"Stainless" comes in all sorts of grades and hardness. Bolts/nuts aren't made from soft material. Stock the same diameter as that little PIN just may be.


This is actually a fair catalogue of the different carbon and alloy HERE.

 

[Basil]

Well, like I said, the load on this little pin isn't tremendous. It limits the travel of a piston when the brake system is "off" and the piston is only being pushed by a return spring inside the cylinder bore, so I doubt that hardness is going to be a big issue.

 

[Exotexs]

the person who machined the stop pin for Basil is a machinist who fabricates parts for Jaguars and his own E-type. I'm sure he knows what to use for a replacement material.
