I bought my KP61 after it had sat unused for over 8 years. I replaced the fuel system. Engine and transmission and bled the brakes. But the pedal was rock hard and had little stopping power. "No problem" I thought. And I replaced the brake booster, master, all flexible lines, the calipers, rotors, drums and rear wheel cylinders as well as shoes and pads.
Yep. Same crap!!
Hard pedal and almost no brakes. Just like before I did ANYTHING. The brake booster holds vacuum for days and the vacuum is very strong. The vacuum line is an actual vacuum line and the check valves are new.
My first thought was that the new booster is also no good. But I noticed when I bled the system that the rear brakes bled easily and quickly. But the front brakes required more work. With less flow. I didn't think much about it at the time. But do you think I could have a blocked steel line? I've never heard of that before. And would a blockage or partial blockage to either front wheel after the "splitter" make for a hard pedal? Or would it be more likely in the line from the master before the splitter?
Is this something anyone has encountered before?
This is a U.S. spec 1981 Toyota KP61 Starlet RWD. With stock brakes. Double master. Separate front and rear reservoirs. I'm not yet familiar with all of the lines or where exactly they go. Or if a blocked or partially blocked line would cause a hard pedal.
I cant really drive because I can barely stop.
