Front brakes on my 2010 YZ450F

20 posts in this topic

Does anyone have trouble stopping there 2010 YZ450F? I'm looking to buy a oversize front rotor, and not sure which one is the best? All I can say, is that the stock brakes suck!!!!!

being that it is a heavy bike it needs oversize breaks as soon as you even mention "race" or "track", i have a braking disc and it works great, oversize brakes are a must have on these bikes.

Ya I too thought the brakes were amazing, but my other bike is now 16 years old, I thought it was amazing I could finally do stoppies. So since I don't know any better I think the front brakes are great, and the rear one is too powerful.

Hows that driven rotor? I'm sure its more in my price range. Although I have been fairly happy with the 2010 front brakes but it does fad after some hard abuse. Just playin around doin stoppies it seems to stop working after 3 or 4 and starts groaning.

Well, so far so good. Have about 30 hrs of mx on it so far with no complaints. Did the rotor first then stainless braided front line.

I have an 08, but the front brake system is the same. I went with an EBC 280mm oversize rotor, modern Honda master cylinder, and Honda brake pads. The EBC rotor gave me some of the stopping power I was looking for, but the feel at the lever was still mushy (even after bleeding the system several times). The Honda master cylinder and pads make the feel at the lever much firmer and requires no more that two fingers to stop as fast as possible.

Does the Honda mastercylinder bolt right on to the Yamaha or does it need to be modified ?

Wow. I must ride like a girl. I think the brakes on my '10 are pretty great.
Me too. I saw MXA said the brakes were weak, but i only ride with one fingur on it now!

It bolts right on. No mods necessary. That newer crf master, with built in linkage, works really well. The brake line does exit on the opposite side, but the brake hoses on the Honda and Yamaha are almost identical.

I had to carefully bent the banjo fitting on my stock Yamaha brake line just slightly to give it the correct angle ( the Honda master cylinder has the brake line coming in the back, while the stock Yamaha has it in the front). Other than this, there were no issues.:excuseme:

I switched to a 05 front caliper and dot5 hi-temp fluid. The 10' front caliper has much smaller pistons( which I'm sure are lighter) and less surface area to bite with. The caliper was cheap $50 delivered to my door off ebay. I couldn't see spending $250 on an oversized rotor kit!

I have to agree, brakes on these new Yamis aren´t that impressive. :excuseme:

No they do kinda suck, I put on the EBC over sized rotor and new pads and they were only better not good. So I out a HONDA master cylinder on and they got alot better but there still not as good as my Kawi brakes were. I have a braided line on also. Does different brands of brake fluid make any difference?

No, nor does the level of DOT standards that they meet. (DOT 5 should be avoided because it is a different base. DOT 3, 4, & 5.1 are all compatible) The DOT gradings are primarily an indication of the temperature tolerance of the fluid.

All fluids are incompressible, and one will feel no better than another. Brake fluid is hygroscopic (absorbs water from the air), so if the fluid is old or has been exposed to air a lot, it can contain water, which will turn to steam when heated, and that will act like air in the lines.
