Mastercylinder question...
Discussion
Hey Guys
I installed the pedals and master-cylinders today. My concerns are:
1) The clutch pedal is only screwed in 3 turns onto the MC pushrod - and pedal is already vertical. Is this ok or should I screw it in a bit more?
2) The brake is screwed in all the way on both front/rear MC. It is still NOT vertical, but inclined forward about 45degrees. Also, on full brake application, it hits the rear chassis bar behind it.
The MC are the new 'Evo' types...
Thanks

Have you checked out
http://www.ultima-gtr.info/index.htm Think the build cd is pretty OK for this part also
This will provide the answers you need, I like the pedal covers BTW Also check you have the pedals in the correct mounting holes as this will I think dictate your positions/angles for your clutch and brake pedals

Mine has the lower pivot of each pedal as below.
Clutch - middle hole
Brake - rear hole
Throttle - front hole
Rear = closest to the bulkhead
The adjustable pedal ends are both similar with about 1/2" of thread on the driver side of upright.
All pedals are roughly level across their faces and angled towards the driver by about 7 degrees.
Hope that helps.

I have taken the pedal positions from CJ's site: throttle and clutch closest to driver, brake all the way back (near bulkhead). However with the new MC, there may be a difference in pushrod size, which is why the pedal hits the rear chassis frame...
I will experiment based on other suggestions and report back.. thanks

The build manual I have (2011) itself has a degree of confusion as it has a photo showing throttle in hole 1 (nearest driver) Clutch hole 2 brake hole 3.
It then has a 'click for diagram' which shows Throttle hole 1 ,brake hole 1 and clutch hole 2.
From the OPs picture it would seem to need hole 3.

I've also noticed that the brake pedal upright easily contacts the chassis, but have been proceeding under the assumption (soon to be tested) that this won't happen once the system has been bled. In other words, with pressure in the lines, the pedal won't be able to move that far forward despite heavy braking.

I think I came to the same conclusion when I installed mine. Ken
As Graham said, you'll get virtually no movement on the pedal, if you want a lighter feel, you'll get more travel, then fit smaller master cylinders.
This is a good guide to setting up balance bar braking. http://www.rallydesign.co.uk/article_info.php?arti...

Ok great... onwards then...
And Ken - since you are ahead of me, do let me know when you bleed the brakes and to how it affects the movement of the pedal.
Will do. As others have said, there should be very little pedal movement once the system has been properly bled. "Wooden" sounds about right to me for this car, though I'd characterize the feel more as "race brakes". There isn't a lot of pedal movement in the Formula cars I've driven nor should there be. For that matter, I'm expecting the clutch to be much more race-like than street car-like - also fine with me in this context.And Ken - since you are ahead of me, do let me know when you bleed the brakes and to how it affects the movement of the pedal.
