Default Truggy brake setup question

What would be a good brake setup for a Losi 8T 2.0 for a slick hard packed clay track. Like 70% rear 30% front? Or even 50/50

I like 50/50 or even a slight bias towards the front on slick tracks. More rear bias will loosen the rear of the truck up, which isn't always good under heavy braking (think about trying to drive a 2wd car where all the brake is in the rear). A lot of it is personal preference, some people like a car that's a little loose on entry so they can throw it around. Start at 50/50 and go from there. That's what those handy little brakes adjusters are for

Yeah, definitely bias even or a little towards the front. You don't want your rear end passing you if you're on the brakes in a turn.

I like having around 70/30 against the rear. I feel too much frontbrake will both cause it to understeer and itll brake too hard.
With alot of rearbrake you can actualy cause it to rotate more into corners. Yea sure its harder to drive but once you get comfortable with it itll start paying off.

60 rear / 40 front. When you have it set right its fun to watch the car brake nicely before a corner.

See?! 4 responses, 3 different answers LOL. Play with it and find something that works for you. And for our next trick, we're going to answer all the "Which engine is the best..." questions.

i ran mine 60/40 rear to front, but for a slick track I could see the benefit of a more balanced braking setup. Or start practicing that Scandinavian flick.

I generally like more rear brake then front, but not a lot. Probably 60rear/40front. you don't need a lot more rear then front because when you brake, the weight of the truck "lifts" off the rear and will cause the rear tires to lock up allowing the rear to rotate around. If you are running too much rear brake, they will completely lock up every time you brake which isn't always a good thing. I had my front brakes set for more in the front and when I would turn the wheels and brake, the truck would just keep going straight with locked front tires even though my wheels were turned. This is what I have experienced when playing with my brake bias.

So, the one thing I hate is adjusting brake bias and trying to go by some crazy percentage by feel. I am all about doing things in a repeatable method and the percentage crap is for the birds. You think someone would take the time to work out some type of repeatable measurement that is not based on feel. I think serpent may have something on their linkages that are different sized spacers. When are the vendors and the team racers going to release setups sheets with this stuff based on real measurements and not percentages? Sure would make life easier.

Well, if brake pads and rotors always stayed the same temp
through out a race, never glazed up or wore any, all track
surfaces were the same and everyone had the same driving
style, your way of thinking may just work.

So you guys can actually measure 70/30, 60/40? Lol

Nah, my 60/40 is your 50/50. Which is Homers 40/60.

Yeah, but you know what, xray seems to have figured out how to tune touring cars shocks in a similar manner to accommodate for ride height differences based on tire wear and they seemed to have been able to measure everything without guesstimating. There is quite a bit of technology in these high end toys that we seem to take the 2 cent approach in the off-road world. Hambone hit it on the head exactly. Take this for example, why not have the linkages setups for the front and rear be identical with the exception of the fuel tubing length. Leave the adjustment knobs out of it and tune with lengths of fuel tubing. At least those are measurable and you might be able to really know what the hell 60/40 really feels like. But, none of the manuals I have seen ever start with identical linkage configurations for front and rear.

Drake did a short vid on brake set-up.
I think you can find it over on Youtube.
That may help out the newer guys who
aren't used to setting up there cars yet.
