I wasn't trying to be.

Have you checked to see if any fluid is coming out at the M/C.May have gotten a bad M/C.

I will check tomorrow to see if fluid is even coming out of the rear circuit in the master. Somehow I doubt it.

For you guys that run the FJ80 master cylinders, does it allow the pedal to go to the floor when air is in the lines before the brakes system is bled? My pedal bottoms out without touching the floor. I didn't think of this at first but now I am confused. It seems to have an awful short travel.

It sounds like you got a bad m/c.Was it new or reman.

It is a reman master cylinder.

Mine was a new FJ80 MC and I didn't have the problems you are describing even after I plumbed in a residual valve

Reman master cylinder from where? If its not a genuine Toyota part take it back and go see the parts guy at your local dealer.

Do you think the additional residual valve is necessary? Would you recommend it?

it shouldnt really matter, if you r rear brakes were dragging then i would say loose that residual, but with no fluid at all,

pull the MC and see if some fool left a nut or something inside the MC blocking the piston movement

I never buy reman cylinders, especially if they are aluminum

alwayzbroken · « **Reply #39 on:** Oct 02, 2005, 07:48:51 AM »

I picked up a new Toyota master that I am going to try. Hopefully it solves the problem.

79coyotefrg · « **Reply #40 on:** Oct 02, 2005, 08:53:04 AM »

did you get your money back on the other one ??

alwayzbroken · « **Reply #41 on:** Oct 02, 2005, 10:39:11 AM »

I am gonna try one more time with the old one after letting the rears gravity bleed all weekend, if it doens't work still, then I'm gonna throw the new one in. I work weekends at a parts store so I am just gonna warranty the reman master and put that money towards something else I need. I got the new one brand new from somebody that I know for 50$ and it has never been installed.

Cool, if I have a lot of pedal travel I'll get one.

Problem solved. It was the junk A1 Cardone remanufactured master cylinder that I bought from the parts store I work at. It must have been drawing air in with every push of the pedal. I installed the new Toyota Aisin master cylinder and had perfect pedal in about 5 mins.

Glad to hear you got it all working...did you end up needing that residiual valve after all?

HA.HA. I used to be a Cardone rep. I returned a ton of waterpumps and power steering pumps, but not that many master cylinders.

I haven't driven it yet, but it has great pedal sitting in the garage. I am loading it on the trailer tomorrow or thurs to go bend some tubes for it so I will find out how the brakes work then.

At the store we have had much better results with Cardone than all the previous brands that we have carried. I was very reluctant to believe that the master was faulty because i know how rare it is for them to be bad right out of the box. I deal with dumbasses that return perfectly good parts all the time becausse they are not smart enough to figure out that the part is hooked up wrong so they blame it on the part.

germ · « **Reply #53 on:** Oct 04, 2005, 12:45:11 PM »

I'm totally with you, I usually will rack my brains, pull every manual and **gulp** ask for directions before I'll consider a faulty part. Like you, I'll try every possible combination before pulling and replacing a brand new part. But, it does happen, like you just found out.

glad you got it going though, let us know how it works.
