On my 1985 Toyota Dolphin 22 re I had a nightmare of issues with my brakes about 10 or 15 years ago. I got the master cylinder changed but the mechanic didn't bleed it so I was driving around with horrible brakes because I'd have to go all the way to the floor in order to stop, so eventually I learned how to bleed the master cylinder where you disconnect the two lines, front and rear lines, and then use a little tube or a salvage brake line about 9 inches long on each of the front and rear line holes on the master cylinder then you put the other end of the of the line into underneath the level of the brake fluid in the master cylinder reservoirs, then you have someone pump the brakes slowly for about a few times and that should bleed the master cylinder of all the air in it. Then you have to connect the rear and front lines to the master cylinder and then they have to bleed the brakes in the proper order probably starting from the furthest to the closest to the master cylinder on the vehicle. My brakes aren't anything great now anyway but at least they stop front and rear, on my mom's 78 Chinook Toyota the brakes were perfect right up there as soon as you start stepping on the brake they would react where mine are now for some reason I have no idea they don't start breaking till about halfway pressed. Don't know if that's an adjustment on the pedal itself or I'm still thinking about that. On the no start issue it would be helpful to know if you mean the starter motor doesn't run meaning the electricity isn't getting to the starter motor or is it a no start with the engine cranking it doesn't start that's an important thing to know to get help with it. In my opinion bypassing the neutral start switch that's on the transmission helped my problem of no start immensely and I've never had a no start ever since I bypassed it I had other things going on originally why it wouldn't start but once I put a wire from the ignition switch to the solenoid on the starter motor I haven't had any issues you might try that. Take care, Pete
