Master Cylinder Sizing
OK Guys I need some help sizing a master cylinder for my car
Big tire in the back, drag lites in the front Brakes Front Wilwood 4 pistons Calipers - 1.75" pistons Rear GM Metric single piston Claipers - 2.5" pistons Manual Brakes Current set up 4 wheel drum brakes. 6 cyl chevy II in the front...Big Ford in the back Car stops good but they do tend to fade away and require adjustment some weekends... 2850 lbs 135 mph I have more motor for the car and do not want any problems going a 150 plus So I need to know what bore to buy. Thanks Dean |
Good luck making that combo work. I had the GM stuff and wilwood and it does not work together. It's been 7 months and still no luck using anything other then all wilwood.
Buy the wilwood for the front and back and the 7/8 or 1 inch bore Wilwood. |

got that setup on 70 nova stops fine ,uses a gm master but i would use a wilwood or strange master 3/4 or 1"

Wilwood disk on the front and drum on the back is fine. It's when you try and mix two diff calipers. One is solid mounted and one slides.
master will not work from my findings. It seems the fluid to move the sliding calipers vs the solid mounted creates a volume issue. I have 3 masters, 2 p-valves and 2 sets of rear brakes. One set the gm small caliper and now the wilwood. Wilwood has had to replace a brand new master for me. Itwas broke right out of the box. I have replaced brake lines and so on. If anyone can make this work please let me in on the process. |
i've put aerospace on several cars, liked it well enough that i put it on my own car rolls easy & stops great
|
what master cyl. have you used? wilwood or fact GM style
|
i use astrange master,don,t need a poportioning valve with it

I was at the track this weekend and looked at SG roadster... Willwoods up front and Metrics in the back...I talked to the guy and he says the thing stops great.. Uses a factory GM Mastercylinder an aluminum one. Has a portioning valve for biased and has residual valves in line.. The only thing that he has to do every day is gets in the car and pumps the brakes up. He said the petal is soft if it sits overnight or for a couple of days. he is not sure why.Said that when they first put the brake set up in they blead the brakes trying to get rid of the soft pedal after sitting and it would not clear up. Once he "cycles" the brakes the brakes have lots of pedal and work fine all day. He is going to see if they have a make and model on the master cylinder.
