Need a spring

[Mr Chevorlet]

Well over the weekend i tackled the front brake job on the truck, I put new rotors and calibers and new rubber brake hoses. I have been dreading doing this but it went pretty good. I pulled off the 4 wheel drive hubs and compleatly cleaned out all the old grease and cleaned all the bearrings,and put new rotors, and then i put my power bleader and blead all the brakes believe it or not, the bleeding went smooth and have good brakes. Thats the part i was dreading. sorry for rambling but i need a pressure spring that inside the hub, Looks like someone put a weaker spring on the drivers side than on the passenger side, Where can i get one. Thanks
