Master Cylinder Hard Lines to DSC

Category: Brakes
Price: $50
Private or Vendor Listing: Private Listing
Part Fits (you may select multiples): Series I
Location (US State/Canada/Int): NY
Item Condition: Used

I just bought a 2004 M/T GT and it has the early model year master cylinder. I want to swap this for one of the 2006+ ones, and to do that need the hard lines. I tried to order from Mazda and they canceled the order, so I don't believe there are any more in stock.

Does anyone have one for a later 2006 thru 2008? Part numbers (I believe) are:
FE0343250B
FE0343260C


43-250 & 43-260

the problem is a lot of salvage yards just snip through the brake lines to take the MC and ABS module off

the other thing to be aware of is the threaded connections, positions, and routings are all different between the DSC and non-DSC ABS modules. So you need the lines from a vehicle with the same ABS module as yours. The vast majority are for the ABS with DSC traction control. Which is in your favor because being a GT it most likely has DSC.

honestly don’t understand why you want to do that though; the early MC has a bleed screw to help get air out and it was eliminated on the later ones.

Get a tubing bender, flare tool, and some tubing/ends. Making hard hydraulic lines is one of those tasks that seems difficult and daunting, but then you get into it, and it's stupid easy.

Yep I knew most of that except the bleed screw. Interesting. The reason I was planning to swap was because the mazda dealer the previous owner brought it to said it needed it. It had mushy brakes and wasn't stopping well apparently. I picked it up anyway and drove it home 900 miles and it stopped fine but wasn't as firm as I'd like.

The pedal does not have as firm a feel as my other one (doesn't engage until halfway pressed) and the oem brakes have 15k miles on them. They are rubber lines vs. the ss ones on my shinka.

I supposed I could try upgrading/replacing the rubber lines and a full ATE flush. Was planning to do this with the MC swap. It was extremely difficult getting Info from the mazda dealer so no idea if they actually bled the brakes but the previous owner said they were better after he got it back. Still not the pedal feel I expected though.

The replacement ones for late 2005 on are much more ubiquitous.

Honestly I went down the rabbit hole last night. I expected it to be more difficult for sure. Tools cost more than I want for this but it's definitely something to consider!

Benders are cheap, and FLAPSes will often rent you the flare tools for free. They also carry straight lines already flared with fittings on them. Know what kind of fittings/flares you need, figure out the length, and they'll often let you in the back to find one that's the right length, or at least within a reasonable margin of error. It's been a while since I've bought either, but I imagine you could get in and out in under $20 and an afternoon.

sounds like you’re covered, but anyone who’s looking to make their own hard lines should consider “cunifer” material (combination of copper and nickel):
