S10 M/C Bleeding Tips?

[68protouring454]

so i am still covered with my set-up right?? hydroboost with the c5 master??? as you said i have boost so i can overcome the other issues going on,where as with a manual sytems it needs to be perfect in all aspects??

I will be swapping to C4 front & rear calipers this year and this is what I will be using:

I don't know how I looked over this, I didn't see it for some reason, but this is EXACTLY what I have been looking for. Do you have any more pictures of this? The Mustang bolt pattern is a bit different than the Chevy, but it is very most likely easy to modify the part to fit.

A small update, but important one. I tried the 3/4" M/C on the car yesterday, without success. At first I thought that I had a huge amount of air in the system, because the pedal would go clear to the floor with only moderate force, the pistons in the calipers were clearly reacting, but it was just not good. I tried three different methods to bleed the system, vacuum, pressure, and gravity. No way there is air in the system. I think what is happening is that the stroke of the M/C is insufficient to move enough fluid to overcome the piston retraction of the calipers. I still may be overlooking something, but I don't think so. I can tell you though, I have had it with the C4 stuff. All of this is a PITA, and I still don't get the thicker rotor like I really want in the front.

Brake makeover time in the near future. Very near future. Can you say "Alcon?"

Mark, that's not good news. Not sure what I should use for a m/c, . You're doing this testing in manual mode now right? Not with the hydroboost hooked up?

Is the S-10 m/c you're trying the 1" bore? That m/c and the 3/4" m/c, are booth of those for a front disc rear drum application? If so, wouldn't the rear port have a residual pressure valve in it?

I had a feeling that Monza master would be too small :(

Yes Jake, IMO you are covered and will stop well.

All the GM QTU's run the front brakes off the rear port as far as I know. The step bore is for extra volume to the front calipers, and is part of the rear piston bore.
I have not yet seen a QTU with a residual valve in it. It must be in the distribution valve unit on those vehicles.

Mark, if the C4 calipers have a lot of piston retraction, you might try a 2psi inline residual valve, and a 21mm or 22mm Mopar master until you get the Alcons.
I'm really likin' that CNC setup Shane linked to though...

Sorry Guys,

CNC Brakes directed me to Johns Mustangs as a dealer. They seem to be very helpful thus far.

HEre is a link to it:

They also informed me that they do have a setup specific for GM. I am impressed because MC changes down the road will be much easier.

Gulp! Now I know why I was a bit suspicious of the brake unit, the price! $325, I'll ASSume that includes a pair of masters, so perhaps it isn't that bad?

I have a Wilwood pedal setup with a bias bar, etc, maybe it is time to look a bit deeper?! Hmmm.....
