Cadence Braking

[MarkCup]

Ive been practicing holding the Cup on the point of lock-up recently (traffic and road conditions permitting of course ), and have pushed passed that point to see how it responds and feels once it has locked.

Each and every time Ive locked up its been the nearside front, never any of the other 3 wheels? It doesnt appear to be a problem...it still tracks straight with minor steering input.

Why would it only ever lock one wheel only? Do I have brakes biassed to one side?

weight transfer probably. it will be the wheel with the least weight on it

cadence braking involves more of a pumpin action really tho

Weight transfer? Possibly, although my experience so far has been on a variety of roads/conditions.

The pumping is what Im trying to get a feel for...you cant always hear that the wheels have locked, so Im practicing so that I can feel and respond to it when it does happen.

Anyone else?

Yeah, all the time on the track. I think they call it "Threshold Braking" that you want to aim for. Just short of locking. Be ready to let up if you have to but you really should be able to hold just short of locking. Everybody used to learn this before ABS came into play.

On the street you really shouldnt be coming close to either scenario though, except in an emergency situation.

there is a defined amount of slip at x slip angle where the tyre gives maximum adheision, but its very easy to go over that.

ON the track its an amazing feeling to trail brake with 1 wheel in the air from 120-60 round a tightning radius corner....yum.

the n/s/f wheel will have slightly less weight on it compared to the o/s/f wheel so thats probably why it locks first.

 

[weight]

that disc may have a warp

plus a million and 1 reasons why it may lock first.

A friend suggested it might be that Im sat on the right of the car, explaining the lower weight and subsequent lock-up on the left.

Last night on the way home; glorious sunshine, blue skies and I managed to haul down from 80mph to zero without locking any wheels, but the front tyres were howling all the way...it felt really good

Cadence does mean "rythmical", so ON-OFF.

basically brake v. firmly until JUST at point of lock then OFF and ON.

shouldnt EVER hear more than a chirp or not quick enough reactions!!

ALSO

1) prolly less grip on inside (gravel etc.)

2) most cars pull slightly left due to camber of road

3) weight (as others said) - even 10stone is 60KG + (or approx. 10% of nose weight) extra over drivers side.
