Hey guys, I've recently started losing brake fluid on my 87 IROC w/ 4 wheel disk brakes. Only problem is I can't find where it's leaking from! I can't imagine any way the fluid could be getting consumed so how should I go about finding this leak and fixing it?

 

caliper and its burning off or from a fitting and flying down the road have someone pump the brakes while its running and check each item seperately

 

It may be filling the brake booster. Unbolt the M/C from the booster and see if there is a bunch of fluid there. No need to disconnect the lines, just carefully move it away from the booster enough to take a look-see.

Are you sure it's just not the pads wearing down?

Brake fluid level decreases as pad wears down, and then is "raised" again when fresh new (thick) pads are installed. Many Many Many folks make the mistake of adding brake fluid inbetween pad changes when there's no leak, and then end up having too much fluid in the resevoir that spills out all over the plavce when new pads are installed.

 

That's gotta be the most likely suspect for a brake fluid mystery leak...

Just loosen up the MC nuts that hold it to the booster, if there's ANY TRACE of "moisture" there, then you need a MC for sure.
