95 accord abs question...

[95cord]

o.k my brakes work fine. i have had no problems out of them but just about every time i get into my car to start it up there is a buzzing sound that last about 1 min and shuts off then my abs light comes on. any ideas?

Don't know about Honda's system, but the Lumina I drive is known for a similar problem that is a defective solenoid in the control assembly for the ABS.

check fluid lvl....if low top it off...also check to see if it's leaking.

if your abs fails your brakes will still work, u should check for the most common failure of the abs system, which is brake dust build up on wheel speed sensor. just clean your sensors and see if it helps.

hey, the same thing happens to me. i went to my mechanic and asked why and he said that it's the abs hydraulic unit. this part usually costs you around 300. good luck.

i'm not going to replace it just b/c of a buzzing noise that last less than a min. only every now and then when i start up the car. my brakes work good.

Pump the pedal about 20 times rapidly with the key off. This will discharge the accumulator. When you turn it back on, the pump should run and recharge the accumulator. See if that is the same sound you hear when you start it. If so, for some reason the accumulator is discharging while the car sits, there is a valve or solenoid stuck letting it bleed down.

P.S. if that's the case your brakes will work fine but your ABS function will not. I have a feeling it is trying to recharge the accumulator when you start it, and after a certain period of pumping passes, it decides the accumulator isn't going to pressurize, so it sets the ABS light.

Something could be hung up just due to dirty fluid. That's why it is so important to do fluid exchanges on ABS systems regularly. Just a little moisture can make valves and solenoids stick, and cost a fortune to repair.
