We bought this set and got it a few days ago.. we have only done 4 brake flushes with it and our new pressure brake bleeder and it works great. comes with a nice little chart that tells you what adapter fits what vehicles.. although not all vehicle are on the chart so a little guess work is in order.. for example, to find the correct adapter to fit an 2009 Dodge Ram 1500, you must look through the Chrysler adapters and narrow your choice down to 2 most common Chrysler adapters and test fit them on the vehicle. Dodge Ram isn't even listed on the chart. Still, a little common sense will go a log way. it also has little stickers on the adapters with the adapter number labeled on them.. i can see these little stickers coming off over a period of time. Thank goodness the adapters are color coded to the chart.. just dont loose the chart. HA!!
