So I got a '72 521, and was really stoked about it for a quick second... I've been really busy the last month, so I didn't have a chance to drive her that much, but drove her 5 or 6 times in the last two weeks. Everything seemed fine, outside of a quirk or two. Specifically, the brakes stopped the truck when I pressed on the pedal. Seemed a bit squishy, but I wrote that off as me not being used to drums. Today, I noticed that one of the tires was a bit low, so I pulled her out of the driveway (to flat ground, the driveway has a bit of an incline to it) and got the tire pressure squared away. Afterwards, I went to pull back into the driveway, and nothing happened when I stepped on the brake. As I rolled into the garage, which I had thankfully left open, I pumped the brakes, (nothing), and finally threw her into gear and dropped the clutch. Not in time, unfortunately, I left a nice scrape on the bumper of the car parked there. I know nothing about brakes, and less than nothing about drum brakes. If I pump the brakes a bunch, a little bit of pressure returns to the pedal, but not enough that I'd trust it to stop the truck. It quickly loses what little resistance it gains anyway. Took some pics--
The reservoir on the right has plenty of fluid, the reservoir on the left is really low. The brakes worked fine last week, what could have happened in the last few days to change that so drastically?
I have various extra brake parts, new shoes etc... is it worth it for me to get the brakes fixed, or should I convert to disc brakes? Keep in mind that I don't have the skills to do the conversion/fix myself safely, so I'd either be paying a shop to do the work, or begging for a fellow ratsuner to help me out. Another thread said it'd be about $400 for Beebani's conversion, but I'm assuming that's just parts.
Thoughts/advice/offers of help?
