okay??? first that doesn't help anyone that's trying to answer your question

we need more info like what is it doing
hows it drive or brake (which i hope your not driving the car with a braking issue)

theres probably a handful of solid diy threads on here, even w/o that information you can pull your wheels and inspect everything like any other car to start with. to be honest if youre feeling "brake problems" the fronts need the work, rear do so little if you did feel anything back there, theyre trashed and the car needs not driven. Id start with the easiest and bleed the brakes right.

bleeding the brakes should help. have you checked the brake fluid reservoir to make sure there is enough fluid? that the fluid isn't dirty?

while you're bleeding the brakes, check the brake pads to see if they are worn.

if those all check out fine and you are still having problems, just let us know.

That isn't true

None of that needs to be done to bleed the brakes on an ABS car

That is the procedure for bleeding the ABS system. The abs brake fluid and regular brake fluid never come in contact.

your telling me that you have a separate reservoir for your abs?

your abs system uses the brake fluid if there are bubbles in the system they can get trapped in the abs unit... the only way to get these bubbles out is to actuate the solenoids either by scan tool or by executing an abs stop. then the bubbles can be bled out normally

the visuals are more for the order of caliper purging. i happened to do it the 91-93 way, and saw this in a book at work.

purging the abs, really w/o fucking with it get a turkey baster and evacuate the abs reservoir and refill with fresh fluid after flushing the regular system, then go and work the abs, theres so little old fluid left after that its negligible.

thanks for the brake bleeding procedure but i have that in both of my brake spec books at work the main issue is there is a noise in the RR and i just wanted to maybe see pics and potentially a parts list of everything that was needed for the swap just to make sure nothing was rigged cause no one wants a brake failure lol

Maybe it's a bad wheel bearing and not brakes at all.

Wait I belive that cb7's with factory rear drums don't come with abs. Only the ones with factory disc brakes all around. So he most likely doesn't have abs on his car if they were swaped in unless who ever did it managed to wire up the abs system which I doubt.

I swaped out my proportion valve to a 50/50 instead of the 60/40 I was locking up the front tires under heavy braking because not enough pressure was going to the back.

I know its not converted to abs nor will it ever its too hard too play in the snow with abs lol

Ever cb7 with ABS has a separate reservoir for the ABS

You don't get air trapped in the ABS unit, its just a line going through it with a solenoid that can move to close off the line.

This is how the system works

nice information ill have to take a look at my coupe to see if there is an issue with that
