Northern Illinois FJ40 Left for Dead (1 Viewer)

Thanks for your help. The calipers are brand new so they definitely don't have any road salt in them. I bleed brakes on numerous cars and never had an issue like this. While holding pressure the brakes bleed perfect. The pedal even feels good, but have no movement on the pistons.

How old is the master?

 

[Picz34]

It's probably very old. I took it all apart and cleaned it and it seem to be working fine so I decided to use it. It's the only part that I have not replaced in the system. I've ordered a new one this morning but won't have it for another week. What I don't understand is that it seems to be doing its job correctly when the pedal is pressed when bleeding the line. The brake booster is brand new but I have not adjusted it. Any advice on that?

Did you bench bleed the master b4 bleeding the calipers? When you bleed the brakes does fluid come shooting out of the bleeders? It should really squirt a few feet with someone pushing the pedal. With all bleeders closed pump the pedal 4 times and then hold the pedal hard and see if it sinks slowly. As far as adjustment in the master and booster as long as you have them set to factory spec you should be fine.

The fluid does flow out of the breeders, but does not shoot out. Where do you bleed the master cylinder from?

That's an important step, as it's a very fine adjustment and needs to be done in a precise way. Check out this video to learn about brake boosters and how to adjust. The adjustment portion starts at the 30 minute mark.

 

[Picz34]

Thank you to all! I've ordered a new master cylinder, when it comes in I will make the adjustments to the push rod. It appears that I will need about 1/2mm gap between the push rod and the piston in the master cylinder at the resting position. I will also do a bench bleed of the master cylinder prior to install. Thanks again. I will let you know how it works out.

Over the labor day weekend I didn't get much work done, but I did put together the windshield, wiper linkage, and motor. I used the rope trick and it was so easy my daughter even helped me!

I wanted to get back to you to let you know what I ended up finding on this. In the below picture I ended up taking out this screw to bench bleed the master cylinder. Little did I realize that this does much more than I expected. After putting the screw back in, the placement of the cylinder inside was out of place not allowing the brakes to work properly. Once I got the cylinder back in place the brakes worked properly again.

Progress is moving along on my FJ40 project. I was able to get all of the brakes working well now. Over the weekend I installed the windshield, roll cage, temp gauge, and engine dress kit for the 350. I also got the fluid changed in both axles, the transmission, and transfer case. This week I will be working on installing the front fenders, and front bib. I ordered a bench seat to install in the back to keep the kids safer. If anyone is looking for some short jump seat I'm looking to sell (PM me).

 

[Picz34]

This thing is really coming together!

 

[Hogan]

New job on your 40, can't wait to see it when it's finished.

 

[Picz34]

Put the battery in last night and this beast came right to life! Still have to put in the line for the clutch, have an exhaust made, and put the seats in before its road worthy.

 

[Picz34]

Over the last 6 weeks I've been chasing wiring problems and dialing everything in. I still have to replace the clutch master cylinder and get some better valve cover gaskets. Otherwise I am very happy with how this has come together. I've selected an exhaust shop that will be installing the exhaust as long as the snow holds off.

 

[Picz34]

I picked up the 40 from the exhaust shop yesterday. I decided to have the guy do dual exhaust out the sides. Turned out pretty good and added to the uniqueness of this truck.

 

[Picz34]

With Christmas over I was able to start into the door patches. Dug into the passenger side door and it turned out pretty well. Only took about 5 1/2 hours to complete. Still have the drivers side door and both ambulance doors to complete.

 

[Picz34]

Work on the other door patch panel tonight. Figured I would upload more pictures to help others in the future.

 

[tstepp920]

I paid someone to weld in some door bottom patch panels for me. He lapped welded the damn things. Now i need to start over.........with someone else that can actually do it correctly.

Im interested in your rear bench install. What seat are you going with? I want one but also want to have 3 point belts on them for when my girls are bigger.
