burban I understand your concern with the brakes issue said:Not 100% true. If you use rear drums and no combo or proportioning valve, you WILL get rear wheel lock up way before the front brakes are even starting to work. Standard disc/drum set ups use a combo valve to delay the rear brakes because drums need much less pressure to operate than discs. I don't think I need to repeat the safety issue with omitting the combo valve on a stock set up.

Tommy, have you ever installed a Wilwood M/C or spoke to one of their techs? You say it WILL lock up the rear drums, yet mine works fine. I didn't just go humb dumbing around with my own engineering, I consulted the manufacture and followed their recommendation. I have no doubt in my mind that your info may be correct for a stock application m/c but the m/c that Wilwood is selling has brake bias built into it. Check it out on their site they have it in plain ole English. I know where you are coming from on alot of your brake posts and for that matter appreciate it, but if you aren't 100% sure about something you shouldn't post it. At the same time, on the street I would prefer not to be rearended by some joker that read on the internet that he could do away with his prop valve and whatnot, as he was installing a power disc m/c on his drum equipped manual brake car. I know it is a catch 22, and I hope that anyone reading doesn't think I am trying to bust your balls or something.

Now in your situation were you keep bringing up the subject about the combo proportioning valve and what not, I dont know where you are going with that. I have installed many of these master cylinders on 200mph promod cars and some of the fastest 10.5 cars and they never had an issue with combo valves or stopping. If you replace all of your brake lines on your car and you are putting on a wilwood master cylinder, the paper that comes in the box tells you what percentage of the pressure will come out of which ever port it says. If you dont replace the lines or the stock proportioning block it works just fine to hook them right into the master cylinder the way that they are in the car. If you use a stock master cylinder then no matter what you are doing it wont be right.
burban said:No not mad, just dont want anybody confused by all the talk about combo valves. Some people have questions about how things work and then after everybody puts their ideas or thoughts in then everybody is still scratching their heads. I dont want to sound pissy because I am not. I am sorry to come off that way to everybody.
