 |  Subject: How can the brake delay be tested?  Fri Feb 24, 2012 4:12 pm | |
| With the front wheel off the ground, I give it a good spin and apply the left brake lever. The tire stops immediately with no delay, even with a light touch. Is this normal? Shouldn't the delay valve not apply the front brake for a second or two? Or, is the valve applying just a little force that would not affect the brake if the bike was on the road? Is there any way to test this valve? Thanks

| Interesting. I'd imagine the only way to know would be on a rolling road where you could compare the breaking force of each wheel.
Your experiment seems to prove that there is some leakage of pressure to the front but maybe its reduced when compared to the back brake. |

| The service manual says the following: This model is equipped with Combined Brake System. Check the rear brake operation as follows:
Place the scooter on its centerstand.
Jack up the scooter to raise the fromt wheel off the ground.
Operate the rear brake lever. Make sure the front wheel does not turn while the rear brake lever is operated.It goes on to basically to say make sure no air is in the system, then start changing out parts. If this is the only test, my next step is to bleed the system. The delay valve is around $110 shipped. Ouch! ')] [/url] The brake fluid levels are good, but the fluid is brown. So, I'll flush the entire brake system and go from there, but I sure would like a better test for the valve. Anyone got any experience with this? |
