View Full Version : Brake Bias
Whats normal percentage of rear to front, ie rears work 50% as well as the fronts
Just need a ball park figure to get mine roughly set up
gonna be shed loads to the front probably, most modern (cough) cars are
it should be around 60-40 front, but with a stripped rear and a heavy engine in the front, id say 70-30 dude!

should be 70 front 30 rear
to get a rough setting:
car on stands, all four wheels off ground
get friend to lightly push the brake pedal till you cant turn the front wheel
adjust bias so the rear locks up just after this point
impossible to give you an answer as your car setup and tyres will affect it all.
You want the rears to lock ever so slightly after the fronts on a wet/slippy road (easier to modulate). Then from there you can wind on more (for more tail happy trail braking) or move more bias up front to generate a safer braking experience.
I know you can't give me an exact figure, but bias valve is swinging free atm, so just want a rough figure that i can then set the ar up from that on the road
the standard bias thingy? i thin so that the first nust is just up against the bar is about right...
Well at std bias the rear were locking up, couldn't adjust it nuts were seized tight, so cut it off, gonna make a backet, and a bit of threaded bar, so its permanent adjustment, not load sensative adjustment

im getting rid of the bias valve.. its a crock of shite.. sticking a willwood lever in the cockpit lol..
the lever enable you to manually adjust the bias... why would the likes of us need a bias valve...how many of us lug family in the back lol
2 levers, one for each system ;)
Toying with the idea still, but its ££ all the time.
And why do you want a bias valve in the cockpit, your car never even sees the track
there is a factory 'bias' setting, but you need to be able to measure pressure at the caliper to use it.
best option lunner, bugger about with it till you get it the way you like it.
im away to sort mine a little bit! locks the rears under heavy breaking!
yeah and in the mean time brake heavily on a wet road, going down a hill and end up going down sideways.
Will get a mate over and try stan's method,a nd then fine tune it from there
stripped the rear seats out again today for a laff, bloody sheffield hills pay no heed to bias settings, back keeps locking up all the time now!lol :roll:
loosen the bolts ont eh bias valve off, mine were seized, hence my current problems
nah am just gonna boycot hills! the missus can walk to wherever she want to go from now on, am off back to the flat! :twisted:
