How to disc conversion?

Post by JB » Fri Oct 17, 2008 10:22 pm

Its probably been said/done many times, but the info i want i can't see.

The marina conversion i believe you need the hubs,discs,calipers,caliper mounts. a modified / rebuilt master cylinder and a reservoir. i also want a servo. what servo can i use? i found some info for this on minor mania, which was from the street machine mag. but doesn't seem to mention the PCD difference.

is it right that i would need to replace all the brake pipes?
where is the best/neatest place to fit the servo and reservoir?

I know there is a ford disc conversion.
Do they use sierra/cortina/escort hubs etc?
Does the same work need to be done on the original master cylinder?
What machining / engineering work on the parts are needed?

what other reasonably priced disc conversions are there?

Does it work out cheaper to get the maching work done by a workshop or buy off the shelf conversions?

nb:i like a good bargain, and have deep pockets and short arms.

thankyou
Jon

Keep an eye open on ebay there are always disc conversions coming up fore sale. The Ford one uses Sierra. As for the servo the Marina pedal box has every thing you need otherwise its a remote one. You would have to change the break lines to the front because they would have to go to the servo. Im not sure but the flexey hoses would have different threads depending on the callipers.

I don't think so. There are a few pipes you will need to change, because of the different route taken by the brake fluid between header tank, master cylinder, servo and front discs.

where is the best/neatest place to fit the servo and reservoir?

I fitted my servo towards the front of the driver's side of the engine bay, with the horn mounted on it - works well. The header tank in my van is up as high as possible on the inner driver's side wing. I have a header tank with a screw thread, less likely to leak - mine was from JLH Motorsport, and they also supplied the parts needed to make the connections to my master cylinder.

what other reasonably priced disc conversions are there?

JLH do a vented disc conversion kit, which I believe is good, though expensive. You do get what you pay for. Bear in mind the engine you have in your Minor; the discs need not be top spec if your engine and style of driving don't call for instantaneous braking lol

i have a second hand jlh disc kit on my moggy and it was soooo easy to fit and looks great, i.e parts all made really well. expnsive yes but i learnt the hard way that sometines hen you try to do it cheaper it ends up costing more in time and parts....
in fact i have another disc brake kit sitting on my shelf to prove it. i spent about 400£ on it and would be lucky to get £250 for it now.
cheers, michael.

Jon.
Are you sorted ?
I have a copy of instructions for fitting the Marina disc conversion and also a copy from Pratical Classics some time ago.
send me a pm if they are of any use.
Cheers. Nigel

SO much easier and so much less expensive to fit -Wolseley 9" front drums ! They are certainly more than adequate for any sane road use of a Minor. No servo, no header, no master cylinder modifications - fit in an hour each side - and they use the standard wheels ! No brainer really.

Assuming you're determined not to see sense and use the 9" Wolseley drum conversion,(

) then have a look at a recent post "disc brakes for about £100". Makes interesting reading, keeps Minor hubs, and uses simple bolt-from-front discs

Where's that LA - can you post a link ??

Bloody hell that was difficult!! Did I say recent post

Posted jan 26th 2007 under "useful tips". Why doesn't it come up on search- disc brakes for about £100??? You should remember it Mr Ecosse-you posted a reply to it(not regarding the W word either!!)
