I've realized long lever brakes for my XB8.
This is a solution that widely improves the braking feeling. So I'm not talkin' about "braking power" which is enough even with the standard short lever linkage, obviously if you have a good servo !
Here in Italy I used to race those brakes (even though I used a slightly different linkage, due to brake only whith 1 front disk....but that's another story...
![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)
) on rally races, which are on tarmac. You know, tarmac has got a lot of grip and no bumps, so the feeling difference whithin the standard linkage was DEEEP!
So I adopted same philosophy on my buggy, and it worked! But buggies need 2 disks, so here's the easiest linkage possible to mantain 2 disks whith F/R repartition adj.
To be really complete, the mod i'm going to describe needs "real" ferodo brake pads; Which I've made glueing xray steel brake pads on a real 1:1 brake pad, and "DREMELLING" them out: these ferodos give you less ON-OFF action, incredible durability, zero fading.
So, the simpliest solution i was able to develop needs:
_ 90° servo horn
_ 2 long type brake cams
_ 3 pieces of steel wire: 2 for long levers and 1 for their linkage
The rear lever is connected on the linkage whith uniball. The front lever needs a long hole (you cannot add another uniball, otherwise it will "force" during movement
![Wink :wink:](./images/smilies/icon_wink.gif)
). The long hole is needed when you give throttle, cause the linkage will rotate on the uniball, and translate in the hole...(it seems complicated, but believe me: it's absolutely EASY AND FLUENT). Try to figure it out...
The red collars allows front/rear braking repartition adjustment.
All that mechanism needs only to adjust the braking end point, improving the servo braking stroke.... i don't know if you understand my english...sorry
Believe me, it's an absolute easy and fail-proof construction!
If you were very sharp and smart modellists (and you are...
![Mr. Green :mrgreen:](./images/smilies/icon_mrgreen.gif)
), you could be able to get the perfect dimensions to build all that linkage PRECISELY in the "bubble" every buggy body have right over the throttle/braking linkage zone!! It will perfectly fits!
Try these brakes, and feel the difference!
