Hello fellows,
This is my first post to the forum!
I am currently working on a BJ40 that I inherited from my dad. It is a 1975 bj40 with poor country specs - which means no front disk brakes, no booster & single cylinder master brake pump (yuk!) among others. I have already replaced the factory engine with a 3BII out of a 1998 Toyota Dyna truck. This engine came with very low mileage and a few other goodies such as a power steering pump and vacuum pump incorporated on the crankcase. This forced me to install power steering and front disk brakes. I got new vented rotors for Land Cruiser and other used parts from a hilux (mini truck in USA) I also got a proportioning valve off from an old disk brake Land Cruiser. I put in a booster and a new 7/8 master cylinder brake pump same as found in a disk brake cruiser, but now when I start the engine in the morning, the brakes are way down and as I drive they kind of start coming up and eventually lock up on me. I have to bleed the line for the brakes to loosen up again. This seems to happen with regards to the rear breaks, but these also affect the front ones.  o you have any ideas what is bugging my cruiser? I am at a total loss. I first thought it could be the booster pushing the master cylinder, but then I took the vacuum out and ran it for a while, and still the brakes kind of charge until lock up. Any ideas are greatly welcomed.
Thanks,
