Brake problems

This thread is now going to prolly stir up a hornets nest, but I feel it needs to be said.
Some of you know I've been having problems with the brakes on the bike locking on solid, front and rear.
Several peeps have looked at the system and on the face of it can find no reason for the faliure
I finally took the bike back to the Honda dealer from wence it came to get Hondas involvement.
They had the bike for a day last week and went through all the obvious checks to try to discover the fault. Un-happy with the results Honda (through the dealer) recalled the bike for futher investigation.
The PCV valve was a prime candidate, but passed all the pressure tests and internal inspection
The front second master was also stripped, again no fault.
The disc's were then inspected for float and wear and the fault then became apparent. This is a very common fault on many Hondas but rare on the BB, AFTER MARKET PADS !!!!
The after market pads are too hard for Hondas disc's and produce an un-even wear pattern to develop. The ossilation this produce re-acts badly with the front secondary cylinder and pumps up and pressurise the whole system, as it's designed for smooth operation. This was replecated on the rolling road where the very slight ossilation can be felt but disguised from road rumble. Once the system was getting hot the bike was then put out to road riding and the mechanic had the bike snaking all over the road with the back brake locking from front brake lever only.
Honda would say the only time they would reccommend after market pads is to go with after market disc's
All the investigation work, loan bikes and other costs have been footed by Honda under their special 5yr dealer warrenty, however I do pick up the cost of putting the damage right caused by me.
They feel the front cylinder is salvagable but the disc's and pads are fooked so the OEM's are now setting me back ?280. If the second cylinder turns out to be fooked, thats another couple of hundred sobs.
There is an old saying "You sure do live and learn"

Wouldn't have happened if you'd bought a VFR1200 !! :eek::eek::eek:

Seriously though this doesn't bode well for manufacturers of Aftermarket Brake pads [and discs for that matter] bet EBC and Carbon Lorraine will have lots to say about this!!

So are Honda then saying that during the warranty period you can ONLY replace with OEM pads/discs?

That can't be right!!

On every bike I've ever owned, one of the first jobs to do is to replace the OEM pads with HH Sintered pads back and front

What discs were you using Mick? I presume the original discs as the bike didn't have that many miles on it??

The disc's and pads I have (or will have ) in my possession will be sent for analysis as I'm a doubting git, and wont drop it untill I have a definative answer.

when i bought my blackbird from new in 1997 I had problems with the back brake hanging on after braking for corners,I took it back to honda, they had it for three weeks and could not find out why it was doing it,I rode it for eight years with this problem.Then I decided to clean the whole bike up and tryed to find out why it was doing this,I stripped all the calipers down and on all the pistons were molegrip marks so i replaced the pistons and seals refilled the system with new brake fluid,I took the bike for a test ride and it was still the same,so then I replaced the delay valve and it was still the same,so then I replced the pcv and it was still the same,so then I replaced the secondary master cylinder and still the back brake was hanging on,so then I decided that the left hand brake caliper hanger looked a bit crappy,so I bought a second hand one from blacks m/c.So I looked at them both to make sure they were the same, the only difference between them apart from the black's one looking newer was the pin in the fibre bush in the old one the pin was not moving the one from black's was moving. I fitted blacks bracket to my bike and there was no problem with the brakes.The pin in the old one I tryed to move with a hammer and punch but it would not move.But now the brakes are working fine :yo:

There's "after market" and "after market" .......

Just look at the cheap nasty replacement fairing panels from the Far East

Oil Filters - another example - pay for Honda OEM - use a pattern part at a slightly cheaper price - scour the internet for a cheap rip off copy - just to save a few pence

But when it comes to brakepads [a critical part of the bike's performance] I'd question who has the better product and Research/Development capabilities - Honda or EBC?

Got the bike back today, and all the parts replaced, and a ?600 repair bill. :eek:

Now in the process of arranging to have the bits analysed, which will be an estimated ?750.

Errr... Concorde was withdrawn because the manufacturer would no longer support the airframe (under pressure perhaps from it's national carrier and close compatriot).

Plus the rudders had developed a habit of some bits coming off .......


Oh and one had a fatal accident connected with (but not exclusive to) bits of metal on runaway due to a US carrier alledgedlly fitting non-approved modifications to it's a/c.

Runway inspections being done at a frequency of one per ...... errr .... errrr..... errrr... oh is it that month again!


Taking off with a tailwind on an overloaded aircraft ... etc.... etc... etc...
:cry:



I seem to recall the brakes worked OK though :-0)
