Thread: SIII Brake Hoses. Metric or Imperial (UNF)

Thanks Uncle Ho but that confuses the matter even further.

The late SIII & stage 1 at least had fittings for flare nuts at each end while the IIB (and the original fitting on my II had a straight thread and washer arrangement at one end.

Having just braved the mild weather to get one out of the car, the ones I have (marked part number MBH 4503) are the 14 3/8" so the standard chassis type.

I might have to do some algebra and work out the length from the originals. (Would this be the formula: =SQRT((A1*A1)+(B1*B1)) where A1 = SIII length and B1 = the 2" wider track ?)

From the SIIA F/C ones, can you tell which ones had the copper washer and which had the flare nuts at each end?

Thanks Dan

I took a long look at your information particularly the SIII and the FC data and have bitten the bullet.

The standard SIII hoses I bought were 14 3/8" just as you said, so have to assume that the mil chassis ones must be the 17 3/8".

When I look at the SIIA FC info I am hoping that the 17" ones are the front ones for the bracket on the swivel (same as SIII).

Taking all that info and with my calculation that the extra 2" the swivel sits outboard of the chassis adds less than 1/8" to the length I had ENZED make up hoses 18" long which should give me an element of safety. I also had the hoses made with springs to shield the rubber from rubbing. When I fit them this weekend all truth will come to light.

Once again, thanks to everyone for their assistance!

PS: Slunnie, if you are listening, I did go out and buy a double flaring tool to make brake pipes. Gee it is easy, I always thought it would be two processes. No longer =
