F1 Braking System

[NewyorkKopter]

Hey, do you guys have any pics or diagrams of the F1's braking system? Like pics of the linkage bwteen the pedal and the master cylinder. Thankss

[hurstg01]

I may have some at home, let me look later for you

nope, i struck out, sorry.....

[NewyorkKopter]

ohh man, thanks for trying

btw, do you know if the F1's brakes are boosted?

[carbuilder2002]

Nope Gordon refused servo assistance as it detracted from driver feel and besides it adds weight.

[NewyorkKopter]

oh so the pedal was connected directly to the master cylinder right?

[carbuilder2002]

As far as I can see from photographs yes The rod goes from the pedal through the bulkhead and the master cylinder is fixed to the rear of the bulkhead. Simple direct and very low weight penalty.

Found one -

I was thinking that he was looking for the connection point on the opposite side of the pedal box. I don't believe I have any great reference on that.

I've also never seen a diagram of how the entire system is layed out, but it should be fairly straight forward given the lack of servo assist or ABS.

I was adding a pic for the first part of carbuilder2002's thread re going through the bulkhead

Like you say, I havent seen a piof 'the other side' either

[Peloton25]

Wasn't criticizing your contribution - I just wanted to add my . I was feeling left out since I hadn't responded here yet.

Incidentally, the photographer of that image did request that his photos not be posted here. I think we should respect that request until he informs us otherwise.

heyyy nice pic. Thanks but yea I was actually look for a pic of the master cylinder itself "on the other side"

btw, is there any signifigance to having two rods instead of one connecting to the brake pedal?

[carbuilder2002]

Not having access to an F1 I would assume it has 2 master cylinders as used on the Jaguar E Types, gives you a backup if 1 fails but usually split to diagonally opposite wheels or as on the E one for front and the other for back.
No doubt there are others who will know more certainly than I do.

[NewyorkKopter]

oh so like one master cylinder for the front and another for the rear...it makes sense, but does it have two master cylinders?

[carbuilder2002]

I would assume 2 master cylinders one atached to each push rod, not sure if there will be a balance bar in there somewhere. On the Jaguar there was only 1 piston from the pedal but it linked to a pressure differentiating linkage between the 2 master cylinders. The same system was used on the D Types and Lightweigh E Types as well.
Hope am not off topic to far here lol.

Since Greg will likely be removing the photo he posted, here's another closeup on the brake pedal linkage - this time in XP4.



I think the balance bar is actually the cross bar running through the pedal. It seems to offer quite a lot of adjustment. Given the performance focus of the F1 I would bet that one master cylinder would feed the front wheels and the other feeds the rears.

I'm still searching for an image of the master cylinder side of the equation, but am so far coming up blank. Even the assembly photos of chassis #071 inside Driving Ambition fail to offer any good photo to reference on that area of the car.
