Question: How do I determine which brakes need repair?

This is a hunting truck for me, and the last time I drove it, I heard a clang, and then no brakes period. I had already pinched off the brake line to the driverside front brake caliper a year ago due to leaking fluid from the caliper. I assumed I was using the passenger side brake as well as the rear drum breaks. I was using little fluid, but was having to "pump" the brakes to allow me to stop. I have filled the brake fluid at the master cylinder and no fluid loss, but have nothing, not even a spongy feel. As I mentioned this is a hunting truck that really only needs a "get-by" brake job for this season. Where do I need to start? If I could get the front brakes working, I would probably not fool with the rear.

Well, sounds like your whole brake system needs attention. I can't give advice or recommend to partially repair a brake system, (but I do understand how hunting vehicles are used and that you don't want to put too much into one.) With the master full and having no pedal, I think the master cylinder may have failed. You can bleed the system at the wheels and see if you get pedal. Also, if your friction material broke off in one of the drums, you can get this problem as well. A full brake inspection is really needed to diagnose this. Again, I would strongly recommend to restore the braking system to full operation, even for the environment you are using it for.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
