Good advice, thanks very much, Dave. I believe the flexible brake lines were OK (the brakes worked fine before I swapped everything), but I will definitely re-check more closely when I tackle the job again in spring. The brakes were all working wonderfully before. The brake fluid was long overdue for a change & the reservoir was damaged. I was "freshening up" a lot of the car & I decided to swap out the m.c. & reservoir, pads, calipers, rotors all with new stuff, since I had the new parts anyway. System was bled thoroughly: clear, clean fluid coming out of all the calipers properly, but now very weak braking, even back with the original calipers (which I know to be good from before). Quite frustrating, but I'm sure the solution is simple. Will tackle the master cyl. bleeding first and take it from there. Thanks again for all the suggestions (keep 'em coming if I've missed anything!).... - ed 1982 DMC-12 [11594] 1986.5 928S 1990 Coupe Quattro 20V Dave Swingle wrote: >Good call - I've seen a couple of cars in the past year where the >flexible hoses between the calipers and the body are plugged solid.
