Ok like the title says. I need help with my brakes. Back in June I had my rear passenger side brakes worked on. The problem all started when I noticed a loss in brake pressure and ended up having a faulty brake wheel cylinder ( I believe that is the name it looks like this ) We also changed the parts and such.
Well we only replaced that one side and im sure both sides are original or they were put on together at the same time. The guy said there is a good chance the other side will go. Now it is December and im having the problem again. Braking feels a little odd like it kinda locks up a little. Right now I am about 1/4 below the fill line in my reservoir. My question now is the best way to see if this is leaking is to take the rear wheel off? I remember the guy who did my brakes showed me how and I went under my truck but did not notice anything.
Here I believe is the backside of the cylinder:
Thanks in advance fellows and ladies
