1984 4Runner, 22R, 5 speed.
Extended Stainless Steel TG Brake lines.
I recently installed the extended brake lines, and bled the brakes, they obviously needed bleeding BEFORE I installed the lines, becuase for my lfie with the rig, the pedal has always been soft, and travel is pretty far before it gets a solid feel, I bled the brakes (rear pass, rear driver, front pass, front driver, LSPV, then round 2, rear pass, rear driver, front pass, front driver, LSPV -- in that order) the pedal was SOLID. only about an inch of travel before it was good and solid feel. I loved it, best stopping in the runner since I've had it. Fast forward a week to today. Pedal is squishy again, travels almost as far as before before the pedal gets hard. I keep checking the resevoir, doesnt seem to be leaking fluid, or if it is, very small amount, and I see no evidence of a leak anywhere, not at any of my new joints with the SS lines, not at any loose bleeder screws, not at the master, no puddles in the wheels from the calipers, only thin I hvent checked is rear wheel cylinders, but, like I said, dont seem to be losing much fluid...
Any other ideas?
Possible bad master cylinder?
bad booster?
