Help me organize my brake components...

[Mr Nick]

I'll be receiving my front and rear C5/C6 kit from KORE3 next week.

Going to install a manual master cylinder from 76-77 Malibu, adjustable proportioning valve, line lock, and all new hard lines at the same time.

I want to make sure we hook everything up in the proper order, as my car currently has a combination valve installed... this things will be different.

From front reservoir on MC (rear brakes) hard line down to the frame rail, install adjustable proportioning valve, hard line along frame rail to cross member above axle... and so on.

From rear reservoir on MC (front brakes) hard line to line lock, hard line to "T" fitting, then off to each front caliper...

Sound right?

• Do I need a residual valve anywhere? If so, why?
• Why do some brake systems have the hard line in a coil right after the MC? Should we do that?
• What type of brake fluid should I use?

Lastly, feel free to post pics of your install, I might want to copy it!



Thanks,
Nick

• Do I need a residual valve anywhere? If so, why? Not in my opinion. I've heard of people using them on the rears with C-clip axles and fixed calipers, but with the floating calipers you should be fine.
• Why do some brake systems have the hard line in a coil right after the MC? Should we do that? That was done at the factory to make it easier for the assembly workers to make the brake line connections bewtween the chassis and the body. It's not necessary.
• What type of brake fluid should I use? Good question!! I just use regular old DOT3

I installed my prop valve near the MC.

Why do some brake systems have the hard line in a coil right after the MC? Should we do that?

I just read the other day about why that is, and it's to offer flexibility in the system. It said it shouldn't be tight between one point to the other. A simple loop or coil should be sufficient and allow some flexibility. I read this in one of my magazines, actually I think it was in Camaro Performers and it was answered by a brake manufacturer. Don't know if this helps you out any.

The coils act as strain reliefs for the rigid brake tubing. The (sub)frame and body are not typically rigidly mounted together and as such, move independently from one another with vibration and loading through the suspension. Even if you are running solid body mounts, things still move slightly when loaded, especially in performance environments like the track. No car is 100% rigid in any direction. The coils effectively increase the length of tubing thereby decreasing the amount of deflection per inch and minimizing the stresses at the fittings where the tubing is fully constrained and most likely to crack and fail.

From a bleeding standpoint, horizontal stacked coils are slightly better than side by side vertically oriented coils since air can't get trapped at the high point of each loop.
