More brake stuff

Spent some more time working on the brakes. Finally got the brake booster in. I created a bit of plate which was welded to the pedal box mounting frame. I did a quick measurement and it looks like the booster will not be in the way of other things. I wont know until I re-mount the engine.

I have also mounted the clutch master cylinder. It is reasonably low on the pedal. I am hoping this will not create to "heavy" a clutch. It is about 4/5 the way down, the original toyota was 1/5 the way down, the pedal. From the pictures you can see I am stuck with this configuration unless I get out the grinder and move a structural member in the engine bay. If the clutch ends up being to heavy I will relocate it. The clutch master cylinder is also mounted on a slight angle, this is so i get a smooth clutch compression as the pedal runs on a slight angle.

Next job is to get the diff cleaned and painted. Also to start mounting the brake lines and fuel lines. Once this is done I can put it back on wheels and start the task of wiring / re-wiring the motor, dash and body.

The brake stuff

Wow the second post in the same night. I must be busy (I wish progress was as good as the posts). So what we have in these pics is the brake master cylinder and the push rod that activates it. Also you can see a bolt being measured. This is roughly the size that the other end of the push rod fits for the cylinder.

To my suprise and thanks to Charles it looks like this step is going to be a lot less painful than first thought. I was thinking I would need to fabricate something that fitted a 10 mm bolt thread and then fit a tube to a spring to create something to spring back the 6-ish mm head that fitted into the master cylinder from the orignal brake booster unit. The pedal should take care of the spring back.

The basic idea going to be used is to take a 10mm bolt of the correct length. I am thinking this will need to be at least 100 mm but should be less than 140 mm long (more measuring required). Cut the head off it and round it out to fit the master cylinder. I will chop the front of the old brake booster (not pictured) to give me a mounting plate for the master cylinder. This plate will be welded to the car frame to stop it moving.

Sounds simple, hopefully the execution is as good as the description.

The steering mounted

Well here is the steering rack mounted. It looks a little high and to far forward. The problem is that the springs (the blue steel) will be in the way if it is moved further back. After some discussion and more research it looks like the above rack is to big. It is a cortina rack in a 100+ frame. The reason it seems to big is my location of the rack is very limited (I should have pushed the springs outside the frame not inside) this means that the joint in the rack is outside the plane of the arm rotation. I am hoping that an escort rack will solve the problem. I will need to make sure I get all the bits this time. eg: All the rubbers, the rod back to the column and any extra CV joints.

Also in these photos I have attempted to take photos of where I think the column will go through the firewall. Although it is not ideal, it looks like I will need 3-4 uni joints and a bit of magic matching them. This is yet to be worked out, but the general idea is that it will come through the wall about half way down and over to the right of the wall. It should all make sense once I cut the hole and push the rods through.
