Rear brake "thud" since recall work performed

[53driver]

Anyone feel a difference in their rear brake since the recall work?
Mine is definitely different, more responsive (but yes, there is new fluid).

What has me intrigued though, is when I step on the brake more firmly than gradually, I feel a "thud" in the rear area.
If I go gradually, no thud.
Is that air in the system working its way through?
I know it wasn't there before the recall work.

I am going to check all fasteners and fittings tomorrow in the light.

Open to ideas so when I get back to the dealer, I can have an intelligent conversation.
Cheers,
Steve

So many smart-azz comments just waiting in the wings....they'll wait until the Rally.
Speaking of Wings - you get an F6B yet?

53 it does sound kinda like you may have something loose. Smart to check it. I don't know what they could have left loose on moving parts though. They shouldn't have had a caliper loose. Could be a piston sticking on the caliper. I've seen those act like that. Like you talked about I checked all my stuff the next day just in case. I don't trust anybody. Oh by the way. I don't think air in the system would act like that. A low pedal or lack of braking would be more the result of air.

Sorry about those comments Tony made about Saorla. Totally unprofessional and unnecessary. I'll speak to him about it. Things like that need not happen on this forum. Can't believe he went there.

It's a good thing I'm a fully trained Jedi - only using my "moderator" powers for good, not evil......

If you still have your bike and it has a center stand; put it up on it and get it in gear (running) and then have someone pull in the clutch and step on the rear brake; while you're looking underneath near the rear wheel/caliper assembly. Maybe that'll help you pinpoint the problem...

Brilliant idea! Thanks. When it quits raining.....

After having the recall done, and having read this post I went out to experiment. At moderate speeds (40-50 kph) if I apply the rear brake sharply I notice a slight "thump" as the decceleration actuates the front brake through the link system. The thump comes from the front, but can almost be felt through the brake pedal. I would presume this was always the case, just didn't notice as I didn't go looking for it... and I don't use the brakes in that manner under normal riding.

I don't use my brakes that way either - normally - but the test pilot in me came out after someone else did maintenance and that's when I noticed it.
I'll go review where I felt it from - thanks.

If you have floating rotors check to see that the rotor is not loose on its hub. Floating rotors do just as implied. They float on the hub and are attached by small puck like discs ,about the size of a quarter. If these pucks wear and get loose the rotor can actually rattle or thump on the hub. Just a thought.

I would hope with 18k on the odo and still plenty of wear left on the initial brake pads, I haven't been killing my pucks enough to wear them as you noted, but it's definitely worth looking at! Thanks.

I'm fairly certain 53 does a F.O.D. walk down of his driveway to prevent such occurrences...
