Introduction:
Hello, I am new to both this forum and cars. I have little to no mechanical understanding of cars. From poking around a few posts it seems that most present on the forum are veterans to the world of cars. Any info to my current predicament is greatly appreciated. Additionally, if there are any tips/ basic information about cars that you feel everyone should know please feel free to impart some of your wisdom.
Situation:
My car was taken to the shop by my father who suspected something was wrong with the rear right brake of my 2005 Honda Accord ex. A day or so later ( I was not very involved with the whole process) I was told by my father, who was told by the mechanic (I'm assuming that all that work at garages are mechanics) at the garage, something was wrong with that piston in the caliper and that when the brakes are used it the piston will...... do its... job..... but it wont return to the state its supposed to upon being engaged, resulting the brakes getting....stuck.... I think. He also mentioned that it was something wrong with the fluids that help engage the pistons. This information is all gathered second hand from someone whose understanding of cars is only slightly higher than my own. So I'm sure those that have a thorough understanding are probably scratching their heads right now. Below I've attached the paperwork we received upon completion of the repair. It might be a long shot but I'm hoping someone who is more knowledgeable about these things can tell me if anything looks off about the repair cost, and whether or not I could have saved myself the money by doing it myself.
