Let me start by saying that I'm no expert and learned how to do this by reading through this website and a few others. I didn't follow the directions in the shop manual either but still managed to get it to work. That being said, I thought that my experience in changing the Master Cylinder could be helpful for someone who has never done it before.
I bought a new cylinder here: http://www.autobrakecenter.com/13044...0-p-23534.html
I paid $46 with shipping and it came in two days
1. Remove the dashboard. Instructions here: http://www.toyotavantech.com/forum/s...hboard+removal
2. Remove "Air Duct #3. There are 2 screws holing it in, one on the far right side and one in the middle.
3. Remove "Air Duct #2" and then "Air Duct #1". There is one screw holding each in. You can leave "Air Duct #1" in the dash, don't worry about pulling it all of the way out.
4. Remove both of the metal brake tubes an open ended wrench
5. remove all 4 nuts that hold the brake mast cylinder on as well as the "Vacuum Check Valve Bracket" (thin metal piece with small and large hole in it around top right bolt.)
6. Remove both of the bolts from the top of the brake fluid reservoir.
7. At this point you can suck the brake fluid out of the reservoir with a syringe to make less of a mess, but I just used a large tupperware to catch and spilled fluid.
8. Pull out the master cylinder with the fluid reservoir still attached by the two tubes.
9. Over a bucket or Tupperware disconnect the two tubes from the old master cylinder by squeezing the taps together with a par of pliers and slide on the new master cylinder
10. "Bench bleed" the master cylinder by pushing a screw driver into the end of the master cylinder to depress the cylinder. While depressed have a friend hold their fingers over the two holes where you connect the brake tubes. Then release the screw driver. Repeat this until you have fluid coming out of the holes.
11. snake the master cylinder and reservoir back into place and replace the 2 bolts holding the reservoir and the 4 bolts and the "Vacuum Check Valve Bracket"
12. Connect the two brake tubes
13. loosen one of the tubes just a bit and depress the brake pedal. While still depressed, tighten the nut. Repeat this until fluid comes out and then repeat for the second tube.
14. Replace the air ducts and put the dashboard back together
15. Top off the reservoir
and if you want to do it by the book, you can download the the shop manual here: http://www.yotavans.org/community/ti...RAKESYSTEM.PDF
