Safety concerning brakes

[blacklightning]

I have a set of the Web Mini boards. It came with a spacer to raise the height of the pedal. I have used it for a panic stock on 2 occasions, and it worked perfect.

pedal spacers

There are several mentions of spacers on brake pedals - unless the bottom of the pedal misses the floorboard a spacer only adds to how high you raise your foot to apply brakes.

But sometimes and inch or less is all that is needed and that last inch of pedal travel is pretty important. The rubber pad on my pedal overlapped the mount and hit the floorboard about a half inch and the mounting bolts also hit the boards. When I added the spacer I made certain the new mounting bolt heads were well recessed into the mount. I guess I picked up about 3/4" more clearance but it is enough.

The problem that most folks don't realize is the Spyder does not have full pedal or pressure on the first pump, it won't get a hard pedal until two or three pumps. All Spyders are like that and that's why BRP went through the trouble to add that safety feature on their boards.

I think some folks are misunderstanding what you said. In a panic stop with ABS it is always best to mash the pedal and keep it mashed until you stop. The pedal will, however, depress further if the brakes have not been applied before hand to build pressure in the system. Even my old 1972 Nova would lock the brakes up on the first hard press of the pedal, but it would go to the floor. If I pumped it a few times, the pedal would not go to the floor as the pressure was built up.'Pumping' the brakes only gives you more skid control on non ABS vehicles.

You are exactly correct! :thumbup:
Mash the pedal, and hang on to your hats! :yikes:

But usage of the bikes, has shown that pumping the brakes does get you a bit stouter pedal...

In a sudden emergency stop....you may not have time to pump the brakes....so hopefully one hard shove does the trick ! :yikes:

I'm sorry but this makes no sense to me whatsoever. I don't think your 72 Nova had ABS, so why is this in the discussion.?????.and PUMPING the brakes on an ABS braking system is a NO NO.........JMHO.......Mike :thumbup:

Mike... My 72 Nova barely had brakes. They were drums, not disks. I added the Nova to the discussion to point out that even in an old ass car, with a tiny master cylinder, you can lock the brakes up without pumping the pedal to increase the hydraulic pressure. On any modern vehicle with ABS, pumping the brakes only stiffens the pedal response. (i.e. the pedal does not go to the floor).

Any computer controlled ABS is best used by hitting the pedal as hard as you can and letting the system control the braking.

Sorry if you misunderstood my post.

I am frequently amazed and impressed by how good our brakes are! Gotta love 'em !:thumbup:

It does, trust me I know. Spyder stops almost on a dime when you mash the brake. With the Brembo's on the front of the F3-S, I have lifted myself off the seat. It sucks when a cage left turns in front of you. Saved my bacon though.

I have had to stand on the brakes twice so far, and the Beast has lifted both my wife and I off the seat. I would never pump the brakes on an ABS system. Just stand on it and get ready to pull off the road when the guy behind you is coming at ya.

... Just stand on it and get ready to pull off the road when the guy behind you is coming at ya.

Excellent advice.

I am usually pretty good with my situational awareness, but if I have to jump on the brake hard, I always glance in the rear view to make sure there isn't a cage about to bounce me on to the road from behind.

Thank you for sharing with all of us how your 1972 Nova compares with your F3.

:agree: :clap: :2thumbs:
It's pretty amazing just how quickly these bikes just hunker down, and stop, when that pedal is mashed!

Hi Chris,

Re: Any computer controlled ABS is best used by hitting the pedal as hard as you can and letting the system control the braking.

^^^^^^ This. I am amazed that anyone would advise pumping the brakes. It will only increase the stopping distance.

I've had to use the ABS system on my pickup a few times; she shudders & shakes but she stops.

Not wanting to try it by no means, but I can tell you in a cage that if you pump your brakes on a panic stop, it will almost always negate the ABS. It is designed to pulsate at a fixed pressure on the pedal. It can then do it's thing and pulsate based upon what the wheel speed sensors are doing. And I'll bet the Spyder is exactly the same.

So, it sounds like you can pump the pedal a few times to get a firmer pedal, and it may or may not negate the ABS. Or you can step on the pedal once for all your worth and hold it and let the ABS system do it's job and hope it's enough. Huh!

And in reality, if it actually was a panic stop, how many of us would have the presence of mind to pump their brakes? I think I would be more apt to just stand on them.

I agree, in a panic stop I did not have time to double or triple pump. I had a couple of very close near wrecks ,once with my wife onboard.:banghead:
I'm using a hand brake on my 13 Rt and was to the point of being afraid to drive it because the lever would just about bottom out and not stop as effective as when it was new without double pumping.:banghead: Thinking that it was in the Hand Brake system , I Bled it a couple of times with no change. :banghead:Talked to ISCI and they swapped master cylinder with no change after bleeding a couple more times . I put new seals in the slave cylinder and Bled a couple of times with no change. :banghead:In my shop I would have a hard pedal or lever, but as soon as I would take it out for a ride it would require a double pump.:banghead:??????? According to the service manual and some on this board the dealer has to bleed the main system, but I decided to bleed anyway. All you are doing is swapping fluid and flushing air, what the hell does Buds have to do with this anyway?????.I bleed a couple times with no change. I find a new master cylinder on ebay NOS for $100 bleed and it did get rid of a slight mushy feel ,but when I take it for a ride the pedal still goes half way down and no hand brake without pumping.

I decided to take it to the dealer and let them hook to the Buds and bleed .In talking to the Ahole service mgr I let it slip that I bled the system and he immediately said Brp wouldn't cover under warrantee and that all the Hand Brake systems are the same way. I go ahead and leave it and 2 wk later and $400 4hr labor I drive it home and No Change.:banghead::banghead::banghead:. I call when I get home and he says he drove it and that's the way they all are (BS) and to bring it back and they would look at it again. I also have a 2014 Rt and the brakes don't need double pumping and the hand brake also work's without double pumping.

I buy a set of rotors and sintered pads from BahaRon and put the rotors on take it out for a ride and brakes are perfect also hand brake perfect with no double pumping. I put the sintered pads on and the first time I get on them hard I thought that I was going over the bars. :yes: All this took most of the winter to sort out and in the end I think that I had about 3 problems at the same time. I think that it had a little air in the system ,the master cylinder leaking a little and the rotors running out a little( letting the pucks move back making the brake lever move farther and making my hand brake run out of stroke requiring a double pump.

In my opinion if everything is working as it should you shouldn't need to double pump.

Sorry this is a little off topic but I wanted to respond to the double pumping.

The new Brembo brakes on the 2014 and 2015 RT are a great improvement over the other brakes used on the prior year RT models.
When you mash on the brakes you stop a lot faster and smoother than on the other model RT. Thge control and smoothness is a great improvement
I am glad BRP put Brembo brakes on the new RT. My ski doo had had Brembo brakes and it really helped stopping distance and control.

SPACERS

For anyone wanting a spacer (aluminum) just contact John at Seal Floorboards and for $10.00 (Shipping Included) he will send you the correct type of spacer and two longer (correct size) screws that will raise the pedal a little and still go through the floorboard opening.
