hey how many check valves are we supposed to have between our brake booster and intake manifold??

BRAKE BOOSTER & VACUUM TUBE. Fits: TOYOTA | Village Toyota Parts

this diagram shows 2 if im not mistaken... or is 44730F just the part that screws into the manifold? this could be my whole brake issue im having... i wish i still had my old engine available!!! sadly to say its long gone... and theres not many if any at all of our trucks floating around my area...

thanks

 

one way check valve

Not sure about the diag. but all you need is the one on the firewall.

 

agreed. Never heard of nor see any point to two check valves.

 

most of the time there is a check valve at the connection to the brake booster...

 

Some cars put it there, still only 1 check valve tho. Toyota puts them in the middle of the line in the 80s-early 90s

 

thanks guys!... figured out the whole braking issue... seemed my rear lspv failed and is not letting any fluid to the rear brakes!!

 

that'll do it, glad you figured it out.
