Brembo Rear Brake Upgrade

[CRAIG4FSU]

Anyone do this upgrade to your RS? The rear brake feels mushy compared to the twin disc front brakes.

I've not done it, but I'm sure there are some who have. I don't use the rear brake enough to worry about the feel. It does what I want, which is provide some trail braking and leave it at that. You might try changing the pads to a harder compound and flushing the fluid before buying a new caliper and see if that improves the response. I put EBC HH on my R rear caliper and the brake felt good under normal riding conditions. If you've gone this route and still not satisfied then maybe a better caliper might be in order.

I guess it all depends on how you ride, but I agree with you.
I put HH pads on my rear brake (2006 Bonneville) and it improved the braking a fair amount. Not a night and day change, but enough to make it worthwhile.
I also mainly use the rear brake for trail braking.
As you suggested, if that's not enough then maybe he should make the change.

Maybe some others will get in on the conversation and be more helpful.

Hi
Regarding The Rear Brake would it not be better to put Softer Pads in rather than Harder ones as the harder ones will take more force to bite and possibly Glaze up quicker. A mate had a issue with a Norton Commando US Spec and found that the problem was that the Disc was Chrome Plated for the export bikes which was not the case for local markets which rust easily! But they Stop as the Pads Bite into the rust on the Disc Surface!!
He is coming in to my shop today to Grind Off the Chrome on My Big Lathe,

Just a few alternative thoughts to add to the conversation which are much easier options than upgrading the calipers .

That’s an interesting thought. I’m wonder if there’s a lot of info on different rotor and pad combinations. Certainly easier to replace or try than a complete replacement of the brake system.

Brake fluid can degrade if it has over heated and feel "mushy" after. Complete replacement, rather than "bleeding", with new, uncontaminated fluid should solve if that's a probem. Also would use a higher temp fluid such as replacing DOT 4 with compatible DOT 5.1 (Not DOT 5). Also, if you have any of the old reinforced rubber hydraulic lines on your system, replace with steel braid lines. The old rubber lines actually expand (inflate?) which feels mushy.

Another thought have you checked that the Pads are not Glazed if so a flat surface and some 120 Grit sand paper will remove the surface But Do Not Breathe in the dust!! You could also try cutting a couple of Slots in the pads to get water off the disc quicker Again a face mask is .a good idea as some pads have Asbestos in them and other nasty stuff.
Hope you have some results soon.
