    Hi,

    Apologies if this topic has been covered before but I need some advice...

    The pads on my new blade were in need of replacement....

    I have replaced them with Brembo SC pads as I had always used these on my R6...

    Ever since replacing them my brakes have felt rather spongy!! I can't quite remember how good they felt before the change but was wondering if anyone could shed some light on this for me? I had Goodridge hoses on the R6 so maybe some better lines may be in order or just maybe a bleed?

    Any advice would be very helpful ;)

    Must say the first thing I noticed when getting my blade was how good the brakes were compared to my other bikes so I would say they may need bleeding.

    I just wasn't sure if its the pads I've used or the heat sinks from the old Honda pads that I have re-used....

    Don't want dodgy brakes on that weapon tbh!!!

    I would start with a Caliper clean and also clean the disc up .I have tried all the usual brands of sintered pads and the general feeling is that the Honda items are just as good and if that fails and its non ABS then perhaps a fluid change and bleed would not do any harm .

    Do any of you know if the caliper mount bolts are stretch bolts or can they be re-used with some Loctite??

    The general consensus from the track day riders amongst us was that you are able to reuse them. I think scooby mentioned this?

    Ok, cheers for the advice! I did wonder if they were stretch bolts as they are hollow! I can imagine a huge amount of force being exerted on those 2 bolts under heavy breaking... Would not want to see the consequences if one failed!!!

    It's personal choice dude, if your not comfy with it? Replace them. Your the one riding it at the end of the day. Just don't hear of many failing, that said, my boy in our fitting shop wouldn't make me some high tensile bolts because unlike manufacturers, he couldn't garuntee them :)

    another honda scam ;)

    the bolts will be fine,no need for loctite,but i do put a little copper slip on them.

    must have had my calipers off 0ver 50times without issue.

    as for pads,the honda o/e pads are very very good,might just be your new ones aren't as good,but a good caliper clean,line bleed wont do any harm.

    1st port of call is to get the brakes feeling good!

    What grease do you guys use on the pistons.. Red seems to be the fav! I have a selection of grease in the garage but no red...

    Copper slip,
    Lithium
    Multi purpose

    Any of the above any good?

    Molly slip or graphite greases are good, they have a high temp melting point. :)

    Cleaned pistons, bled the lines and it's feeling way better! Would I be correct in thinking that you start with the caliper furthest from the master cylinder for the bleed? Also noticed a bleed nipple on the master cylinder....?!?!?!

    I bled all my fluids yesterday as they were looking a bit dark, and once I had done it the brakes felt so much better.

    Brake fluid is Hygroscopic, meaning over time it absorbs moisture, even in a sealed master cylinder. Fresh brake fluid is non compressable, but as it absorbs moisture it becomes compressable which can give you a spongy feel. This is why all fluid manufacturers and vehicle manufacturers recommend changing it every two years.

    I have just swapped the standard pads in my 2013 for Brembo SC's and the standard pads don't have any copper grease on the back, they just have a metal plate that clips onto the new pads.
