EVO Brakes

[ClassicBertha]

I wasn't sure where to post this question, so as I ride a 1100GS I thought I would start here.

I keep hearing about EVO brakes, and some love them, and some wouldn't touch them with a barge pole, to the extent of reading about someone on this site removing their EVO system on their GS ADV.

My question is: What exactly is an EVO system? and How does it actually work? I have heard some mention the word 'dangerous' in the sentence where this is concerned. is this true, or not?

I currently do not have this problem, but I would like to know the facts because I am interested in later bikes with a possible future purchase that only came with the EVO system on.

Any pointers to good reading material that can tell me will be greatly received also.

Cheers

Brad

It's the "SERVO" brakes that are the problem. The clue to the problem is in the name .

Re:"EVO" brakes

Suggest you have the wrong title.

You probably mean ABS or possibly servo brakes.
Many (Mostly deluded) riders believe they can ride better without ABS brakes.
Suggest you look at this site for an informed view:

http://faq.f650.com/GSFAQs/TheABSFAQ.htm#Can a Good Rider REALLY do better than ABS

Many other BMW riders hate the servo brakes.
They cite the occasional problems encountered & silly BMW prices for replacement parts, forgetting Motorworks have so many of these parts, they are selling them.

On a personal level, I love them.

My only regret is that my bike is no longer available with fully integrated brakes, which were dropped after 1150 models because of rider resistance.

Car drivers are a fairly reactionary lot, but they do seem to appreciate the advantages of modern brakes and the extra margin of safety they provide.

Motorcyclists, by and large, believe themselves and their skills to be above the average for mere mortals, (a contradiction it itself) and that these "superior" skills will dig them out of the sewage in an emergency.

Personally, I would prefer to put my trust in proven technology, expecially on a wet or diesel covered road where the risk of a lowside is very high as a result of too much rear brake in an emergency.

Caras don't have electrical failures that cause brkes to disapear (reasidue braking).

ABS = good
Servo, linked = bad

 

[sockpuppet]

ABS = good
Servo, linked = bad

I concur. I'll probably do the same as Timolgra and dump the servo before I go to Africa as I really cannot do with a servo problem when I am out there.

At £1400 new (or £500 s/h) but at 10kg in weight it really would kill the finances having to replace it - I'd rather rip it out in the comfort of my garage some backwater using the tools I took with me.

They carried on with servo brakes untill 2007 on the 1200 models, servo brakes are hardly proven on bikes, no other bikes have them, its not about being superior, they are carp because when they fail, unlike a car they stop working instantly without warning, and they do stop working, then post about how clever the system is when you sail past those traffic lights into that junction

BMW no longer fits "electric" servo brakes - point proven.

I think you maybe getting confused between abs which was never a problem and electric servo ( cars use vacuum servo) that was/will be a problem

Most but not all modern cars use vacuum systems, & anyway it just leaves you without servo, not without brakes (any more than a car does as anyone who has been towed will know.)

BMW withdrew servo & full integration because of reactionary criticism.
It has always amazed me they continued with ABS, since the only comments made are critical, & the majority who are quite happy with it are ignored.

Point remains proved. Motorcyclists are a reactionary lot.

Most cars are not marketed as "unstoppable". A failed servo really does make you unstoppable

Given that the brakes with the servo unit removed are powerful enough to stop the bike and ABS systems don't need a servo I can't really see the benefit it provides.

Now I have seen/understand how the servo unit is supposed to work which is fine on a road bike (i.e. the rest of the 1150 range) but not on a bike intended to go the less populated parts of the world.

You expect BMW to sell something that people don't want? I am sure that the servo issue was either due to the fact they got fed up replacing warranty units or that people told them they didn't want the servo. I reckon it was the first.

We never said they weren't. We just said the servo is shit. Which it is.

 

[Myke Rocks]

servo is shit?

How do you know?

 

[ELIMINATOR]

I know, I had two fail under warranty, luckily on both occassions the failure was about 5 seconds after pulling away, no warning lights, just no brakes. Despite others saying the brakes are OK without the servo working, I say they are not.

Technology for technolgy sake, German arrogance in denying there was ever a fault.

.

I've never heard of complaints regarding ABS ?? But heard plenty of servo complaints.

I've also heard of a couple of cases of servos failing on K1200 because they drained the battery while stop and start riding through london in the rush hour.
So if thats the case thank god for a reactionary viewpoint, instead of being led like a sheep.

Servo failures

Have you done a statistical analysis?

Shouldn't BMW have done so, & recalled all bikes with a servo to have them removed if they are dangerous?

They did so when the rear wheels fell off the first r1200 models sold.

Since the deleted the audible horn at the same time as the servo, I presume this was as a safety measure as well, to stop other road users dying of a heart attack!

 

[Steptoe]

Have you done a statistical analysis?

!

No, same as you haven't.

I'd guess BMW have and thats why they came to the decision to pull the servo option.

Deleting an expensively ( for BMW warranty dept) troublesome option bears no relevence to a rear wheel falling off recall.

 

[Steptoe]

Shouldn't BMW have done so, & recalled all bikes with a servo to have them removed if they are dangerous?

!

That would be an admittance of liability......

There were recorded accidents which the riders said were due to the brake problems, but it would have been impossible to prove in a court of law .

Do a search of all the BMW forums and see how many servo problems show up.

 

[Myke Rocks]

deletions?

What about the horn then?

 

[Steptoe]

What about the horn then?

It's illiegal to sell a new vehicle without a horn And i don't think a failing horn has caused anyone to shite their pants.
