De-ABSing the FD

I still have ABS but the master cylinder has been changed to a cylinder out of a Mazda 929 .It is slightly longer and has a bigger bore. Works very well .

Were there any issues with the shared fluid reservoir on the 929 MC? I've never looked at one to know..

Instead of the stock 15/16" it's a full 1". I've thought about doing that for a big brake kit to push the extra fluid, but I was told it wasn't required. I guess now would have been the time to do it since I'd need to bend the lines anyway lol.

I've used the cheap flare tools with a bit of success but have since started having a local brake specialist cut and flare all my lines. I use coat hanger or similar to lay out the lines and get a length and take that and the tube nuts in and have them make up the lines. The line is higher quality and has proven to be more corrosion resistant than what I'd bought through Summit and the flares never leak. Stainless line is also an option if you want something that looks really nice. Just to be clear, this shop isn't one of the $99 four wheel brake places. They do mostly fleet service and do top rate stuff. Any decently large town should have something similar in the area.

Also, working in the OE production world, one of the tricks we use on leaky flare fittings is tighten and loosen the fitting 4-5 times in succession. Many times this will help a flare that's not quite right to get itself sealed up.

here are some pics of the ABS delete kit I make, I use automotive bundy tubing that's double flared , with zero flex line.. the kits now come with all steel fittings, no more aluminum. kit includes an adjustable proportioning valve so you can fine tune your brakes as well.
I also have a kit for the 929 master cylinder as well, I will post some pics .
everyone that's installed these kits loves the quality and fitment of the kit

why someone would sell a flexline ABS delete kit is beyond me.. what an epic fail in so many ways! brake fluid gets really hot, Teflon line gets soft, and there goes your braking!

Why do you exclude the front brakes from your proportioning valve?

Yeah, the $250 soft line kit is a bit of a laugh... I'm currently up in the air on whether I want to get the Wilwood 2 inlet, 3 outlet, prop valve, or just use the factory one and T the front brake lines.

Because you want full pressure to your front brakes. The rears you want to set so they lock slightly after the fronts do. If the rear brakes lock first, the car will want to swap ends on you. This could be considered a bad thing in the middle of a corner.

OK good to know. I wasn't sure, I just hooked it up the same way my buddy did his. Thanks!
