2008 Monster S4RS rear brakes feel weak

I am new to Ducati's and I test rode a 2008 S4RS today with low miles. Everything about the bike was awesome...except for the rear brake. At first I thought the pedal needed to be adjusted, like maybe it was at weird angle. But then I got up to about 15-20 mph and pushed the rear brake pedal as far down as I could and it barely slowed the bike down at all. MY question is, is that normal? The front brakes felt super strong. I would expect more from Brembo brakes.

After the test ride, the owner stated that all Ducati bikes with single sided swing arms have weak rear brakes? I find that hard to believe. Can someone help me? Please tell me the rear brake can be improved?

The biggest issue here is that to bleed the brake properly you have to remove the caliper, turn it right side up or use a vacuum bleed on it.

With the bleed screw facing down the air can not escape in the line or caliper. Physics 101.

With a proper bleed it will work just fine especially with the rear brake on your model. I have the wimpy Brembo on my S2R800 and can lock the rear wheel easy.

The excuses given ceases to amaze me. I'm afraid for America.

Okay, so having the rear brakes not working on an S4RS is not normal? I want to buy this bike, but I want to make sure the brakes can be fixed. How do I proceed with the seller? Have him get the bike repaired first?

If it's the bike you want do it yourself. That model is the bad boy of Monsters. It wouldn't be a deal breaker for me. There are always things that need attention on a used bike.

It's just time and brake fluid. If you can't do it then have him take it to the dealer for a proper bleed.

Is the fluid low in the reservoir?

Okay, the fluid did not seem to be low. Don't know when the last time it was flushed. Bike only has 5200 miles.

Low miles for sure. I've looked in Texas for one as the prices are more reasonable. Left Coast prices are insane, won't pay it.

Should change every two years. I'm sure it will need some love.

Yep, everything here in Ca is expensive So you don't think it would be anything more involved like the master cylinder?

Do you have to take the rear wheel off to remove the caliper?

Hard to say. If the rear caliper has not been off it could be or just a good bleed. I would bet it needs a bleed. I've never had a bad MC unless it was a 20 plus year old Honda or something.

If you like the bike, get a good price for it then buy it. Remember, Service is expensive so anything you can do yourself is a plus.
