Electronic Wedge Brakes

If some of you Western movie lovers think these look familiar well they should because it's the same principle as used on wagons and stagecoaches, except the electronic wedge uses kick azz electronics and an innovative wedge-shaped connection to provide the sort of stopping ability that our caliper brakes can't match.

I'm still dreaming of the day when technoligy retreats to the point of using "scrub brakes" like I have on one of my old Sears pull-start mini-bike .... I have an old go-cart frame from the early 60's that also has the far superior scrub-brake set-up that I plan on restoring once I retire.

Those look real interesting Squid.....In theory it sound slike they will be far superior to pistons and hydraulic fluid. But what happens if a wire isnt grounded or something shorts out? I know that hydraulic brake lines can brake or other things can happen but it seems that electronics woudl be alittle more fragile.

I would say that this is the answer.

With each brake unit operating independently from the others, it also means the electronic stability control can be programmed to operate on a much finer calibration, without the typical pulsating effect evident in some cars today.

Rather than loosing both the front or both back like you would with a busted line now you would only loose one brake.

Loosing one brake on the front and still having the other work could be extremely detrimental to your health... say having the left front caliper grab and the right not - how many peope have that good a grip on the steering wheel to keep you from jetting off to the left - which many times is oncomming traffic?

Nonetheless, I'm sure the software will be smart enough and the hardware setup so that if it's told to brake and it doesn't, the system knows it and thus makes some adjustments to compensate.

Ya think? I'm not so sure with 3 brakes just how bad it would be. I mean there are times when I'm stopping hard that only one of the front brakes are working because you hear the grating sound from the other one and the wheel doesn't jump out of my hand.

I would think that if one of the brakes was out, the system would be able to compensate for it...

I had 3 wheel brakes on my circletrack Stockcar .... the right front rotor was machined down to just a hub and the brake line to that caliper was plugged..... mainly for removing right side weight and also to help "loosen" up the car to assist throwing it into the corner, Although it was VERY noticable, the power steering and front to rear brake praportioning valve kept it from being too freaky ..... it would stop somewhat staight, even in "panic" situations fairly well .... as long as to had a good hold on the wheel.

I read this issue. Wedge brakes are cool.. ... The faster you are going, the more efficient they get!

Makes sense to me and then when you throw in the the ABLS and anti lock braking system technology on a system like this I bet you would need a warning light just to know that one of the brakes wasn't working.

It's hard for people who have never driven a car or truck built before the mid 70's to truly understand how easy driving is now adays. I know that every time I drive my 56 or 72 on the highway it really makes me happy to get back in the Titan. Those two don't have power anything......well the Landcruiser is suppose to have power brakes but they are still drum so panic braking is not advisable or fun and if you drive through a mud puddle you better remember to dry them off.
