Hi All, quickie

 

I have just had new brakes and fluid installed and I have been told that they were bled to the callipers. Should they be bled to the ABS pump or am I barking up the wrong tree?

 

Or do you do both?

 

Cheers.

Pre '94 models have two bleed nipples on the ABS unit (marked F and R). Make sure you

follow bleed order and procedure as per FSM:

I always do the full bleed (calipers and ABS) when changing brake fluid, gives the whole

system a fresh fill.

Much obliged.

 

Would it cause any damage to the pump if they weren't bled to there? Just that mines dumped all it's fluid and the pump was running with the ignition off? Does it pump to a certain pressure?

 

Cheers.

Normally the ABS unit should be bled first as it is the first item after the master cylinder, having said that provided enough fluid was bled though at the 4 calipers then the abs will most likely be bled ok, if not it is ok to just bleed it after.

 

The abs unit should not run continuously unless there is a problem with the control circuit, and especially with the ignition off, as I said on your wanted thread its sound like the motor relay is maybe sticking or the abs ecu has an issue.
