Dual brake conversion

Post by Peterr » Tue Mar 01, 2011 12:37 pm

I'm sure this has been covered, but couldn't find it.
Can I bolt a Marina or Ital dual circuit master cylinder (assuming I can find one) directly onto the Marina single circuit servo?

jiversteve - a belated thank you for pointing me to the answer. I also am Marlin not Marina, and following the thread I will be investigating my front suspension clearances to see if the clonk on braking can be eliminated. I think you put those photos in Pitstop.

As its a Marlin, check that the Master cylinder reservoir does not obstruct the steering rod. Otherwise fit a a remote reservoir.

Ahh the suspension clonk.
Yes it was me. Quite alarming clearances in Mini upper wishbone. Covered at viewtopic.php?f=13&t=2907&p=38176&hilit ... ake#p29150
worth checking the upright top swivel whilst you are there.

Otherwise front suspension noises are from in order of significance,
Tie Rod bushes: Change to Superflex bushes, check that the tie rod hasn't reduced in diameter or the chassis hole worn oversize.
Trunnions: If they are not greased frequently or are allowed to stand wet and dry, corrosion will set in and destroy the thread perhaps in both the trunnion and upright. Might be salvagable by fitting new trunnions but new uprights or Walford trunnions (now very rare) are the only solution if they are high mileage.
Lower arm chassis mount: Change the bushes to Superflex.
Shock absorber: Ex Herald, Not usually noisy but they might be.

If I am stating the obvious sorry, and perhaps this belongs on the Marlin forum, Sorry FMM users.

Similar apologies to Marina owners, but thanks for the tips anyway
