landrover598 Posted January 26, 2007 Share Posted January 26, 2007 My landy has a rangy front axle and twin brake pipes, I'm about to replace the flexi pipes and route longer ones allong the radius arms ( in preperation for suspension changes) It would be a bit easier / neater to run a single pipe down each arm, so can i get rid of one of the two pipes ? Is there any advantage to the twin pipe setup ? Anyone got any comments ? Quote Link to comment Share on other sites More sharing options...
jwriyadh Posted January 26, 2007 Share Posted January 26, 2007 The two seperate feeds provide redundancy in the front braking system. If you suffer a pipe fracture you still retain working front brakes. jw Quote Link to comment Share on other sites More sharing options...

If you'd like a better system [in my opinoin] swap to Defender callipers and master cylinder. mike FOAK Knockers I can cause trouble in an empty house !!!

landrover598 Posted January 26, 2007 Author Share Posted January 26, 2007 I'm allready using a defender master cylinder, and slpit the pipe going to the rear of the vehicle, to use as the secondary front circuit, so it wouldn't be hard to remove, but then there will be an open hole in the calliper Quote Link to comment Share on other sites More sharing options...
Les Henson Posted January 27, 2007 Share Posted January 27, 2007 Just blank the hole (m10 fine thread ?)with locking compound to prevent leaks. Les. Quote Link to comment Share on other sites More sharing options...
Lewis Posted January 27, 2007 Share Posted January 27, 2007 On my friends RRC he has single flexi to the the axle end and then a copper tee peice and two copper pipes to the caliper Lewis Quote Link to comment Share on other sites More sharing options...
Turbocharger Posted January 27, 2007 Share Posted January 27, 2007 If the two ports are quite separate, I think blanking one port will give you half the braking power :S Quote Link to comment Share on other sites More sharing options...
Mark90 Posted January 27, 2007 Share Posted January 27, 2007 I have known people T one pipe into two to go into both caliper ports without issue. Blanking ports, hmm, not sure, depends on the caliper circuit, which I do not know. Quote Link to comment Share on other sites More sharing options...
rtbarton Posted January 27, 2007 Share Posted January 27, 2007 Only using one pair of pistons will half the braking effort so front/rear balance will be affected. It's quite common for Mini owners to fit 4-pot calipers from a Metro to their cars using a T-piece as mentioned above. You will need a T-piece because the two pots are completely independant of one another. Quote Link to comment Share on other sites More sharing options...
landrover598 Posted January 27, 2007 Author Share Posted January 27, 2007 Thanks for that, i didn't realise the secondary ports provided half the braking, i thought they were just a back up I was going to run the flexi straight into the caliper, but it looks like i'll have to put two bits of copper in there first Quote Link to comment Share on other sites More sharing options...
Andy Posted January 27, 2007 Share Posted January 27, 2007 they do provide redunacy to an extent. on the original fitting there is a front circut & a whole car circut. one side of each front caliper will work if the whole of car circut goes - for a while till you loose more fluid. just T them together into one line, it'll be fine. im told some disco/RR owners upgrade to 110 calipers as they & the pads are larger giving you more powerful brakes.

If one circuit leaks, the design of the master cylinder stops the other circuit losing fluid. Quote Link to comment Share on other sites More sharing options...
western Posted January 27, 2007 Share Posted January 27, 2007 Defenders [including all 90/110] have a I/I split system = front/rear on seperate circuits, the front calipers have a through drilled fluid way to both sets of pistons. RR & Discovery 1 [my also apply to D2] have a I/H split = front only & front/rear at reduced braking power if the front I circuit fails, hence 2 lines into front calipers to seperate pistons Quote Link to comment Share on other sites More sharing options...
Andy Posted January 28, 2007 Share Posted January 28, 2007 yeah the master cylinder stops the other circut loosing fluid too in theory - never seen it work on any car ive had with a leaky brake system Quote Link to comment Share on other sites More sharing options...
landrover598 Posted March 30, 2007 Author Share Posted March 30, 2007 Well i finally got a free, dry day to do this modification. I've replaced the two short hoses going to each caliper with one long one run allong the hockey stick, then into a Tee piece and two short bits of copper pipe Before Now Now i can start work on the front suspension without having to worry about the hoses going tight Quote Link to comment Share on other sites More sharing options...
JST Posted March 30, 2007 Share Posted March 30, 2007 nice work Dave, pipe might be a bit exposed though dont you think to sticks/branches etc, but then no more exposed than what was there before i guess. you will have the same braking force running two pipes to the calipers as the calipers are not fed of separate supplies/chambers, so for any foot pressure the same amount of fluid is still displaced Quote Link to comment Share on other sites More sharing options...
pugwash Posted March 30, 2007 Share Posted March 30, 2007 are cable tied pipes legal for SVA and MOT? 'll be doing exactly the same thing dave, but want to tie down the legality of it first. Where di you get the flexi pipes from as they're quite long by the looks of it! Quote Link to comment Share on other sites More sharing options...
V8RRC Posted March 30, 2007 Share Posted March 30, 2007 Hmmmm....Thats a tidy job you have done there Since I am planning on fitting extended hoses to my RRC now I have seen it done I am also tempted to swap my 2 pipe setup to a 1 pipe system Quote Link to comment Share on other sites More sharing options...
landrover598 Posted March 30, 2007 Author Share Posted March 30, 2007 are cable tied pipes legal for SVA and MOT? My zip tied rear flexi pipe (running along rear A frame) passed SVA Pipes from Llama 4x4 Quote Link to comment Share on other sites More sharing options...
