I have a 77 Toyota hilux with stock brake rotors and new brake calipers and brake pads also has new metal and rubber lines brake booster out of a 84 and my back brakes don't work there is no fluid going threw the lines to rear . Rear lines r blocked off right now but still not wanting to stop good. Trying to figure this out .

 

Do u have a LSPV?

 

Did you disconnect the line going to the rear to see if fluid wasnt getting thru? Or are you not getting movement from the wheel cylinders?

I ask because on mine i went to bleed the brakes and i wasnt getting movement from the cylinders, so i disconnected the line to the cylinder and fluid came thru. I had to replace the wheel cylinders

 

OK so far I have blocked off back brakes for now to try to get front fixed first . Replaced all lines to front metal and rubber and new stock brake pads and calipers on front also swapped the booster and master cylinder to a 84 Toyota set up . Still don't want to stop to go . Probably going to see if I can find a better brake set up for the front maybe off the 80 model if it will fit . I dk yet . Got the truck running ran great for 3 days lol just my luck oil pump quite from sitting so long I guess so now it has a bottom end knock .So now I am thinking about pulling the 20r and the 4spd out and drop in a Chevy 4.8 LS v8 swap . With a auto trans . But got to figure out how I am going to stop it. I got 16x12 wheels with stretched tires 215/55/16s stick out alot . Will have to change that before I put v8 in or it will be sitting on the tires . Lol the brake problem is pissing me off more then the motor knocking.. I dk . Top speed with stock motor is 50 on flat road and 60 down hill . Lol
