Ital/Marina Axle Brake cylinder Q

[IamScotticus]

can anyone say what cylinder size came on the live axles?

[7Westfield]

no idea about the Ital units, but for reference, the cylinders on my Ford axle are .70

[IamScotticus]

Do you need any pressure proportioning devices to prevent locking?

[7Westfield]

well, let's just say that I don't HAVE anything

I'm running a mid 80's RX-7 master cylinder, and it is ok for street + autocross

Scoticus,

 

I have gone through quite a bit to get the drum brake set up on my Ford axle. The brake backing plates are 9" from a Mercury Capri 4 cyl. The drums are Cortina MKII GT (9"x2") The wheel cylinders are stock 71 Capri ones. Most of the stuff is Cortina and lots of Capri Stuff is the same. Go to motomobiles web site, lots of info there for reference, but I got the same ones at Rock Auto.  I don't know what the original back plates were on a Ford axle Seven, still would like to.

 

Best to you,

V

Pic of my drum brake set up..

Pic illustrates my point I made (in Vinman1's other brake topic) on interchangeability of brake systems. Here is the other 9 inch cortina GT brake system around the same time. Note the difference in the outside edge of the backing plate which must match the drum but otherwise, interchangeable. A few mfgs were switching to a more rigid, rolled edge backing plate at the time requiring the drum design change.

Thanks Vin

Heres mine 

I don't have an adjuster on the cylinder, its up top and manually adjusted with a square key.

I also confirmed this to be A Marina, not an Ital, although Cat says its an Ital.  The hub locating key is 3/16", not 1/4"square.

Where some have gotten into trouble on these is fitting Ital hubs on Marina shafts giving the Ital hub 1/16" of space to move in.  Fortunate to not have this issue.

If buying shafts from MOSS or Rimmer Bros one must check this.

That must be why some have sheared the key in the key way.

Does anyone have a source for brake drums on the Austin Marina?  width is 1-1/2, length of friction material, is 6-5/8.   The emergency brake slot on one end of the plate has a tab retained by a funny-looking, triangle-shaped spring.

 

FWIW, my wheel cylinders are 3/4

 

thanks,

sorry, brake SHOES, not drums.

 

Brain fade.

 

you'll be old too, some day.

If you cannot find any, there are relining services. Here is one:

[IamScotticus]

Try Derek Moore at Caterham Midlands ( previously Classic Carriage) 01455 841616.

They supplied the axles to Caterham back then.

 

And there's Skip Harris "The Marina Man"

marinaman@marinaman.org.  He should know how to get them if anyone. 

 

I would say early TR 7 4spd shoes would work  but the more I look into the TR7s axles, the more minor differences I find, so I'm not sure about that.

 

I need them for my car too as spares.

thanks to both of you, I emailed Skip and he thinks he can help;  I thought of relining, it used to be popular, now...not so much.

 

I might look at the early TR7, if I do I'll let the group know what I find.

What are ya using for diff oil?

It's interesting,  Caterham has always written in the build manuals that the axles are Itals, but the narrower hub keys are Marinas', and probably the cylinders too.

I did check dif fluid level and really dind't have to add any, but I use Redline 75W90 in my Plus 2, and that's what I'd use in the 7.  

[Steve in Lititz PA]

BTW, That's a GREAT Hemming's article, and, oh, another By The Way, I was born in Lancaster, PA, grew up there, and now live about seven miles from there. 

 

In my twenty's I had a '66 E-Type (DON'T even think about yelling, I know I shoulda kept it), and needed a fuel pump.  Looked in the JC Whitney catalog, the same p/n for a 66 Jag fuel pump was called out for a Healey 3000.  I went to the same Lancaster CountY Motors dealer mentioned in the article (they sold Healey's) and asked for a fuel pump for a '66 Jag.  They told me they don't sell Jag parts, so I asked them to sell me a 3000 Healey fuel pump.  They reluctantly did...worked like a charm.  Now they sell Mercedes (always did), and Suburus.  Nothing from the UK

[IamScotticus]

What a blast from the past.

I spent so much time in JC Witney catalogs.  So much of thst stuff looked really cheap.  But I didn't care.  It was there.

[IamScotticus]

While on the subject of these, there are two articles you should have, as well as the Haynes manuals for Ital and Marina.

Unfortunately, these aren't about the brakes

These shoes look like mine.

Some things have to be checked to be sure, but the info is interesting.
