I've searched this topic to death and figured why not throw up my actual situation to see what kind of info I get back for real world driving. I know if it was a purpose built race car manual would be the way to go. I also have read horror stories on the Hydroboost. At this point I just want my car to stop and have a good driving experience.

So I'm rethinking my brake system a bit. I'm looking for my vacuum gauge but I think one of the problems I have is I don't a lot of vacuum. I expected a harder pedal because of that not the "spongy" one I have now but maybe that is not the case. Assuming that I don't make enough vacuum I'm looking at other options. Cam is a 242/248 576/600 on a 110 in a Pontiac 466. Car has a mid level protouring suspension and 6 speed with 3.42 rear end.

Currently the car has C5 front and rear calipers and rotors. Hawk HP up front and whatever is the standard pad that comes in a Kore3 kit in the rear. I have a wilwood 1 inch tandem master and willwood prop valve.

I'm leaning heavily towards a CNC dual master setup mostly because Keith at Customworks recommended it (only if power was not an option) and hell if this doesn't work I'll put the car on a trailer and drop it off at his shop :) Long drive but brakes would be worth it!! I also like the simplicity of the manual system and don't like the overboosted feel of older power brake cars.

I expected the tires to be the limiting factor for this setup and right now I have to leave alot of room in front of me to stop and they wouldn't lock up for nothin. I've bench bleed the master and brakes again and have kept pressure on them for awhile with the car off and the pedal stays firm and no leaks that I can see.

My question really is for everyone but especially people that have had both setups manual and hydratech hydraboost assuming working and spec'd ouy properly, what is the easiest to live with????? Or a better question is if you daily driver the manual setup for the summer is it a good feel with a properly sized manual setup?

Thanks for any input or suggestions!!

I've driven @ three different manual brake cars in the last year or so and I just cant convince myself to like them. I just cant see putting big/bigger aftermarket brakes on a car only to have to apply HEAVY pedal pressure to stop even in normal street driving. I know there are some guys on here who like manual because they don't lock up as quick, but they still lock up. I just personally like the feel of power brakes.

Power brakes or no power brakes, no ABS is still NO ABS! Lol

Is that MC what Tobin recommends? Sounds like you aren't generating sufficient line pressure. Pads can make a noticeable difference. I always liked the HP+ is my C4 applications.

Tobin recommends a 7/8 Master I believe from what I've read with the C5 brakes. The CNC setup is just a trick setup and I'm assuming would allow me to get real close to optimum size on the individual master for front and back and then use the bias bar for fine tuning. Conceptually it sounds simple and awesome. I've just never driven a properly setup manual brake car. Hydroboost sounds good in theory but I"m worried about cost when you add in a better power steering pump, leaks, overboosting and reliability.
