 | A brake pipe union reducer
 
 1/4" pipe - 3/16" pipe
  
 found this
 
 http://www.cbsonline.co.uk/product/Brass_7%7C16%22_Male_Union_For_3%7C16_Pipe_BU716M
 
 looks right but says 7/16" which if that refers to the pipe then its wrong, but iv seen that 1/4" pipe has some kind of reference to american 7/16 might be the thread or something
  who knows 
 First person gets a kiss

 | i think what iv linked is correct, i think the 7/16 might refer to the thread on it, iv ordered a couple they are cheap enough anyway, if anyone has any other ideas though

 | right im pretty certain iv found a brake union that will work on my master cylinder, can anyone help me with this
 
 at the moment the OEM setup is basically as follows
 
 
  
 with 12mm unions at the master cylinder and thicker 1/4 inch pipe feeding the abs pump which then runs seperate piping to each corner using thinner 3/16 pipe.
 
 Now what i would ideally like to do is rip out the abs pump etc and use 12mm unions at the master cylinder that reduce down to 3/16 pipe and do the lot in 3/16, like so
 
 
  
 i need the following things answered though.
 
 Is there any sort of bottle neck fucking the 1/4 inch pipe off for 3/16 through out.
 
 also for the rear would i be better t Pieceing at the front of the car and running two seperate lines down for each rear corner, or doing what Ian has and running one 3/16 pipe down the car and t piecing off to each corner at the rear, as shown in this diagram
 
 lastly is there any point in me using a manual bias valve when the biasing is done in the MC anyway

 | what you on about daveylc thats no relevance to any of this lol, if you actually read what the problem is.
 
 the original problem, that is no longer a problem as iv found a solution as detailed directly above your post, was that the master cylinder currently has 12mm metric male unions, with 1/4 inch pipe coming out of it which doesnt match anything t pieces, or 3/16 pipe that i currently own.
 
 But I have sorted that now with a 12mm metric union that houses 3/16 pipe directly

 the only outstanding problem was the best way to repipe inside the car, wether to send 1 3/16 pipe to the back and t piece from there, or t piece at the front of the vehicle and send 2 pipes to the rear.
 
 From what iv found out though one pipe will be fine
