Manual bleed. No fluid coming out of the pump assembly To the front left slight fluid seep to right front good pressure to rear I think. could it be the relays on the pump assembly or the pump assembly. Is there a way to check either. would it make a difference to have the key on when bleeding or start the car

Apart from the difference in the wheel sequence ABS brakes should bleed in the same way as non-ABS. If you are still having problems you may have a blockage in one of the brake lines or one of them may be kinked.

A pressure bleed is a much better option.

Thanks Bill I will try that tomorrow, but I think I only have one bleed valve on the front calipers and two on the rear. If there is two on the front I have missed the bleeders I'm seeing are on the top. Have I missed something.

The 88-90 Volvo 760 has ABS which means it only has one brake bleeder on each of the front calipers and one brake bleeder on each of the rear calipers.

alright attempted the bleed as directed get some pedal no fluid to the left front . Replaced left front caliper did bleed as directed have I think good fluid to all calipers but soft pedal. With engine running pump up and fluid is strong at all wheels, engine off weaker any Ideas? Feel like I have a air leak but see no fluid and have no idea where or how to find it. Had no idea this was going to be this challenging,but have to finish at this point. Going to try to find a pressure bleeder.

I think you still have air in the lines.

Bill
I did the bleed as directed, still no or little fluid to the front left, very little pressure to the r Front. Replaced the left front caliper, did bleed finally got pressure both front and rear still have soft pedal and seems to leak off. Put in gear on blocks and will stop rear wheels but leaks off and have to pump next time. The rear end seems to move a lot, doesn't seem right. Think I will try to find a pressure bleeder, feel like still have air in lines. Any Ideas

Thanks
Larry
