Ok guys. I have an issue and want to confirm my fix before spending money.
I have the stock 260 master cylinder and booster installed. Up front I have 240SX calipers and on the back I have the wilwood setup for an 8.8 rear-end. Before I tore the car apart I had drums on the back and 300ZXTT large calipers up front. This setup worked great with the stock master and booster. But now I’m getting nice air free fluid out of the master and all calipers but brake is spongy and takes 3 pumps before I get the brakes to stop the car.
First pump nothing, second pump slight stopping, 3rd pump locks up the brakes but still goes almost all the way to the floor. If I hold it they don’t release. I’m thinking after reading the stickies my master cylinder is no longer up to the task. I want to upgrade to the wilwood 1 inch. Just want to confirm I’m not missing something simple. All stock brake lines are removed and replumbed with hard line and braided hoses. all stock valving on the firewall is removed and i plan on installing a wilwood porportioning valve once i get the brakes a little closer to operational
any inputs.
