Need some ideas on replacing Brake Pads and bleeding
I am planning to replace my brake pads and also do a full brake fluid bleed. could i do both at the same time? reason I ask is that I am going to use the Motive Brake bleeder and it will apply pressure to the brake lines and i am assuming that it will be difficult to move back the pistons in the calipars when i change the pads and bleed at the same time since there will be that extra pressure in the line. Does that make sense? any ideas?

ALWAYS have pads in the calipers when doing bleeding etc.
If not you have the chance to hyper-extend the pistons and that is a making for a bad day. Don't ask me how I know this ....... Haasman

Put in the new pads first, bolt it all up and then do the power bleed. Do you have all the torque specs, and MB repair/maint. manual info? Sequence for bleeding is RR, LR, RF, LF. Don't let the reservoir run dry! ![]() Have fun, it's a very rewarding DIY project. Hazen Arnold 91 300TE 4Matic 134k mi.

I know about flushing fluid from the bleed nipples on 4 calipars, but how do you bleed the ABS? is there a bleed screw just for the ABS? or once i flush all 4 corners that will be taken care of automatically?

I don't think there is a separate bleed for ABS, only for ASR (traction control). I just did my '95 E300D, with ABS (of course) and there is nothing in particular for the ABS. If you have ASR on your W124, there should be a bleed nipple on the ABS pump, and you bleed it the same way as the calipers.
I see you have an E420 - I suppose you do have ASR. It is described in Stu Ritter's W124 Bentley book. Have at least 2 liters of new brake fluid on hand for a full flush. You'll love the Motive Power Bleeder. Far better than the ol' Mitey Vac for bleeding! Rgds, Chris W. |

Wrap a rag around/under the master cylinder, in case you overflow the reservoir pushing the pistons back.

Speedbleeders
I recommend these: http://www.speedbleeder.com/
I've installed them on all of my cars (no MB yet; I pick it up next week). They are very easy to use. Doug |
