Brake Master cylinder thrust rod?
Brake Master cylinder thrust rod?

Can anyone tell me the length and diameter please?
Thanks

Re: Brake Master cylinder thrust rod?
Sorry for the late reply.
The thrust rod for the R90S and R90/6 have the same part number - ...309. I have a '74 R90/6 in the shop and I'm rebuilding the master cylinder so I can give you the sizing for this one.
5.97mm diameter.
26.50mm length.
Let me know if you plan to spin one up as the ends have a radius and I can give you those measurements and photos if needed.
I hope this helps,
Scott

Fast. Neat. Average. Friendly. Good. Good.
Re: Brake Master cylinder thrust rod?
Hopefully the R25 will be back on the road soon. It looks like you have it close to being figured out.
In my very quick search I noticed the push rod (34 31 1 233 309) is NLA on the sites I checked. Unless Richard can find another used one I'm thinking he'll probably need to turn a new one.

Hi
Thanks that the info I needed.
I will whip one up in the next few weeks.
The end radius shouldn't be an issue..I can figure that one out.
Thanks again
Richard
Re: Brake Master cylinder thrust rod?
Got bored so knock this up. 316 Stainless so should be as good as new.
Thanks
