yes i want to put a guage to read my barke fluid temp .. yes i konw its usless and a waste of time and money ... but i don't need to hear that.. just need ideas on where to place the sensor so that i don't get air bubbles in the brake lie ... and should have have 4 or just one ?

I think one of these would be sufficient, what about doing brake temp gauges as well that way you can figure out where your brake loss is comming from. cool idea thou
