Mushy front brake

Hello, long time observer, first time posting, so please go easy on me. I have a 2006 tiger 955i that I absolutely love. I keep up with the maintenance as best as I can and fix items as soon as they pop up. With that said, I replaced the front pads and wanted to flush the brake fluid with some fresh stuff. I have done fluid flushes countless times on many motorcycles and have rarely run into a problem. This time around, however, my brake lever feels mushy. Not to the point where it doesn't stop, it just feels like there is less resistance than average. It definitely has less resistance than my 96 trophy. Any suggestions? Anyone have this issue?

Remove the calipers, pump the pads closed, scrub the pistons as clean as you can get them with some brake cleaner and a pipe cleaner or something, coat the pistons with some Permatex Brake Piston grease, lever the pads shut, pump closed, lever back, etc. a few times.
Lube the pad pins and the caliper hanging pin with the grease as well.
That should do it and do the same for the rear as that sucker will crust in place and burn up your pads.
How do I know this, you ask...

Hi........welcome to the forum

I've always struggled to bleed Tiger brakes properly, so could be something as simple as a bit of air in the system ??

I would also check the condition of the piston seals. A new set really does transform the brakes.

Safe riding.
Regards,
Graeme.

Had to rebuild the calipers on my 2006 Tigger just after i bought it as the seals needed replacing. I remember having a real issue bleeding the brakes, even with a vacuum pump to draw the brake fluid through.

In the end, I removed the calipers from the fork legs and raised them up as far as I could without stretching the brake lines and bled the lines through again. I followed this up with pulling the brake lever back as far as I could and cable tying it in position overnight.

Next day they were hard as nails & almost 12 months later are still pretty much the same.

I suppose I will try and clean/grease them first. If that doesn't work I can rebuild them. Any reputable rebuild kits I should consider?

I replaced the seals on my rear caliper this week. The seal kit is Triumph part #T2020505, about $42.00. An alternative is Honda part #06431-MA3-405, about $6.00, but you'll need two Honda kits per caliper. Any seal kit which fits a Nissin two piston caliper should work. The pistons on the Tiger are 27mm. Don't take it from me, though; do your own research.

I'm not sure about using grease when when installing the pistons. I suggest using nothing but clean brake fluid. If the pistons and bores are clean and smooth, they'll drop right in. Don't forget to replace the banjo washers if you disconnect the brake hose.

Tying back the brake lever and leaving overnight is also a great idea, as Lee mentioned above.

I don't know about Nissin but every Brembo caliper and master cylinder rebuild kit I ever sold came with a packet of assembly grease.

Good tip for the Honda part number!

I always had trouble bleeding the brakes when I had my 955. It was better when I pulled off the caliper and held it above the level of the master cylinder, thus allowing air bubbles to rise up before I started bleeding

I finally had a chance to tackle the front brakes. I took the Pistons completely out, cleaned them up, slapped some grease on them, worked them in and out a few times, and BAM.....I have brakes!!! Yay!! Thank you for all the help. I could not believe how dry/crusty they were. I suppose I will do that.back.as well.
