[QUOTE="Roberto, post: 707828, member: 8160"] ......................... Yeah, double brake servos etc only change the brake FEEL. The make practically no difference to the actually braking distance. Of course, brake feel is important, but sort out your entire stock system and see if your brake feel is not satisfactory. Then just use steel braided hoses, the feel will be firmer. However, to emphasise again, braking distance will not change. But you will like it better. :) Piston bleeding is where you : 1. Open the bleeder nipple 2. Use a flat head screwdriver to push the piston back into the calliper OS you use the screwdriver to leverage the other side of the calliper, achieving the same effect. All this while of course the brake fluid topup tank is in the fluid reservoir to replenish oil being lost through bleeding. Mechanics don't like to do this because the wheel needs to be removed to get to the piston. And it takes a big more effort than the usual vacuum bleeding. Just tell them you'll pay them more for labour. Do not listen to their arguments that this is not necessary, that it is only done for multipot pistons. It is, and it makes a difference. Shut them up by saying you'll pay them more and just tell them to do it. Normal 4 wheel bleeding cost RM30, here, you can pay up to RM50 and its fair. As mentioned, you'll need more brake fluid for this, as alot of dirty fluid will come out when you do the piston bleeding, and all that needs to be replaced with new fluid. I first read about this here : [URL="http://forums.bimmerforums.com/forum/showthread.php?2062913-Weird-brake-problem-525-E34&p=27153982#post27153982"]http://forums.bimmer...82#post27153982[/URL] [B]Check out the photos and you will be sold.[/B] Tried it out, I had no bubbles on my system before and my oil was good, yet alot of dirt came out and the brakes were better after that. If you are overhauling the callipers, changing the seals etc then this is not necessary of course. [/QUOTE]
