ok so I have my rear calipers on my build, measured up the lengths of hose and working on the adaptors for the ends

decided against banjo bolts as its more expensive, and also heard some non to good reports about getting a good seal

so I look at the threaded bits to go in, but m10x1 are available with convex or concave ends

I dont have the original hoses as they were removed from the caliper and left behind

so what one do I need

i think I used concave, cant remember now. would go check my reciepts and get back to you

Most problems with copper washers on seal on banjos are due to the fact the caliper wasnt designed for them i.e the face of the caliper is a rough casting and not machined flat.

Have a look at the sealing face on the caliper? If it's concave then you need convex hose ends or vice versa.

ok thanks, will try and get a better light to have a look down the hole, my garage isnt supposed to have electric, so only a small lead light hanging from the ceiling.

Convex

Here's an original Sierra rear flexi that I've used.



On one end is a concave fixing and the other a convex. When I got my rear brakes I bought a whole back axle and the flexis were still in it and Ford had fit the concave end into the caliper, which has a convex end. I remember asking about this myself. A quick search has it at around 12-13 Decemeber 2007 and Vindi Andi said the same thing, that he found his this way and that it was common practise on some Fords.
I tried to put a copper washer between the hose and caliper but the recess on the caliper face won't take it because it's too small.

ok thanks, been to the pile of bits today and luck would have it, one of the calipers still had loosely screwed in, a short length of hose, I had a look and got very confused, came on here to ask, and your reply was there


however the area around the thread is very flat and clean on mine, so Im going to go for the banjo bolt method, this makes it easier to install and or take apart again in the future.

now a shopping list of braided hoses and fittings is starting to appear, hmm best work out how to pay for it all LOL

thanks guys

Sierra calipers were available with both convex or concave seats (concave much more common) only way to be sure is to check the bottom of the caliper hole. If you use hoses from me however they have a clever double seat machined on the ends so will seal to either. I would recommend against banjo fittings unless you have a machined face for the washer to seat on.

cheers just found your website and have to say Im well happy, sent you an email regarding measured lengths etc

thought the prices I had from my previous supplier were good, your hoses although being visually different, are cheaper by quite some margin

I can put the calipers in the mill and mill the surrounding area flat and clean no worries

using the screw in fittings would make the job even cheaper, but would force the hose up into the air and look wrong as well as be in the way, as it has to loop back down and run along the frame to the master cylinder and pressure valve

a 45 degree banjo bolt fitting is easier for me. as I can direct the hose in the direction it needs to go
