thanks for the pic Rod,yes it all makes sense now.my rpvs are about 2" from the m/c. not to sure how to work this out so measured as follows clutch first then brake old pedal inner lever opp arm ratio? 7" 2.5" 6" 2.14-1 new 7" 2" 6" 1.71-1 clutch much more progressive with about twice the travel  A little progress  A little progress now  A little progress and brake old pedal inner idler ratio 7" 1.5" 2-1 9.3-1 ? 7" 2" 2-1 7-1 ?  A little progress much less spongy and more responsive but maybe a little harder to push .so have i gone the right way,it feels much better on both clutch and brake,don't know if my ratio calculations a right so i stand to be corrected on those  i won't be surprised to find they're wrong thanks again for any and all comments edit: forgot to say yes bleeders are at the bottom,is this wrong? because of the single leading shoe set up and the hand brake lever this seem to be the way they have to be or did i miss something  A little progress just had a look at fifer's site and now i wonder if my backplate is on in the wrong place,the diagram i found had the cylinder at the bottom not at the side |

Pete (fifer) will know mate.Just remember that air will always go to the top .could get trapped in cylinder ,as I explained on mine.Im not sure if thats the actual prob with yours,but worth a try anyways. Could be a combo of things? Keep us up to date .....Rod

will do , i think i am air free ,as i said we stood the trike up vertically to bleed the brakes, not a very practical thing to do now that it's fully built but hopefully not something that needs doing to often.will be interesting to see how the should be orientated

Bleed nipples should be at the top.
Near side wheel, viewed from front. I ran my brake line from master to the off side wheel then across the axle so I only have one bleed nipple.

thats interesting heres mine from the same place  A little progress the bleeder and pipe aren't interchangable but i'm sure the ones i took of where like this too,will have to look through the scrap and see if i can find them thanks Olds just checked on fifers site and part number listed as bbw 1545 which is what i have got,i wonder Olds does the hydraulic piston point up or down? |

BG i think 5/8 is about 17 which is why i chose what i did but i'm wondering if this is enough to properly pressurise the 2 rear cylinders and 1 front, as morrag said basiclly the same as the car but i dont know what the m/c diameter was or if it had 2 different size sections ,1 for the front and 1 for the rear but at least i know from your experience that my m/c should at least work the rear and maybe run the 2 front discs from the handle bars.
My front and rear brakes are seperate. Don't think I'd like them all to work off one lever, too much front brake on a trike and you can get the rear trying to overtake the front, specially on a gravelly or wet road. |

You sure the bleed cant be changed for the pipe? Your nipple seems more protruding (ooer!) Than olds one and the pic of the one youve ordered.

Inside the ports are shaped for the seat of what is to be screwed into it tapered for the bleeder and op2 for the brake end so I don't think you can change them. I'll try and get a pic later

Hmm. Both the ports on mine are the same. Think the norm for Robins and Rialtos was a feed to offside, single bleed on the nearside and a link pipe between wheels, Kittens, a three way union, two feed pipes and two bleed nipples. Though it shouldn't matter how you plumb it up.
Also seen back plates where the wheel cylinder is mounted at the top and adjuster at the bottom.

yep thats the way the car i took this all from was piped Olds,only 1 bleeder on the nearside. got pics of the ports  A little progress bleeder port  A little progress brake pipe port looked through ebay and most pics have the bleeder at the bottom,i'll have to keep digging into this one although i don't get any difference when pumping the pedal so guess in alright any way.discs are looking tempting though! |

Thought mine were standard Reliant and I have nipples both sides - on the top. But of course I know there's an issue with Reliant axles having to be used upside down with some bikes - mine included - and I've seen something (probably on here) about how to swop the brakes round so they are still right way up.

Both ports are the same, so either or, and I always use, line in on N/S, with link brake pipe to o/s, and one bled nipple, and if you have air collecting you have an air leak!! prob. on return stroke of the M/Cyl. whether you fit the bleeds up , down, whatever, should not present a problem if the master cyl. is higher than the slaves, Morrag

the ports are different ,the bleeder one is tappered away from the port the brake pipe port is raised in the centre.the m/c is probably level with the wheel cylinders and i have rpv's fitted but i don't have air in the system i don't think so for the minute that not an issue but with the bleeder at the bottom does it make it hard to bleed properly when the need arrises. plumbing wise i come out of the m/c into the rpv and then onto a 4 way splitter wich the feeds each back wheel and the rear brake light switch.

Shouldn't the handbrake mechanism be to the rear on a standard Reliant ? If so the rear brake backplate is ounted 180' out . Move it round and it'll put the bleed nipple at the top.
