1989 Toyota Pickup Truck, rear-wheel drive.
Front disc brakes, rear drum brakes.
I use this vehicle on my property for hauling tools and dirt etc.
Last week, one of the brake lines sprung a leak, and I lost most of the fluid in the master cylinder. I still have some braking, but the pedal goes most of the way to the floor and is spongy.
There seem to be TWO brake lines, running side-by-side going to the rear of the vehicle. It is one of these lines that sprung the leak.
Both of these lines go into some sort of small device at the rear of the vehicle. One line comes out of this device and goes to a second device. There are two lines coming out of the second device; one goes to each rear wheel. What is the purpose of this arrangement?
Can I simply crimp the bad line upstream of the leak, to prevent loss of fluid and retain full function of the front disc brakes?
