G'Day,
Sorry if this has been posted before and sorry for the long winded story to come. I am having an issue with my left rear brake. As you can see from the subject, its a 79 BJ and for those who dont live in Costa Rica, RTV or Retieve is the annual vehicle corruption...err, inspection.
So a couple years back, engine goes tits and I get it rebuilt. In the process I request other things to be sorted out, specifically a brake flush (I had the clutch, fly wheel, and throw out bearing replaced as well and they didn't flush the clutch). Anyways, the "mechanic" says I need new parts for the brake in question despite having them maintained (all rebuilt pistons) about 4 weeks earlier. I don't have flip flops on the ground to monitor the process so I take their word for it: mistake on my part. Anyhoo, three months go by and I get my beloved back. They had taken it out for about a 40km test run to make sure there were no issues with the rebuild, to which there wasn't (thankfully seeing the block wasn't machined correctly and the crank didn't rotate on the first go around). With that, my daughter and I pick up the battle cruiser and make our way around town getting things done. As I am passing the shop I look over and think "thank f*** I wont be going their again" and BAM the god damn wheel goes flying down the road, damn truck skids to a stop. Tire bounces across the median and two lanes of traffic only being stopped by a fence. Awesome, thankfully it HAPPENED RIGHT IN FRONT OF THE GARAGE I JUST PICKED UP THE TRUCK FROM! My daughter, calmly, looking at me from a height advantage asks "did the tire just come off", "yep", "that tire?" as it bounces down the road. I just look at her and say get out. As I am storming down the road to the garage, two lackeys pop out, see me and sprint to the tire. In process the owner sees me and continues to talk on his phone and ignoring me, yelling at him. So end state, the truck is sitting on the now scored drum, I have no lug nuts (I found one when i was walking back to the bar for a "cool me down" rum), and no patients for BS.
Fast forward to my first RTV with the battle cruiser and I fail. The fail came from that brake and it is because it doesnt brake at the same pressure as the right rear. Now, I adjusted the brakes and no dice. I was thinking maybe the proportion valve however there is one glaring issues: the bottom shoe is not the same as the other shoes on the truck. This shoe is identical in looks however it is missing the centre hole for the retaining pin. Now my physics brain is trying to picture the piston actuating but because there isnt a force (the pin) acting on it, then the pistons efforts negate itself.
So, has anyone run into this brake issue? Sorry, I do not have pics at the moment as the truck is in the process of having the wheels bearings and rear dif rebuilt.
Thanks
