Rear Brake Caliper Replacement 89 300SE Diff Springs
 

Just replaced hoses, calipers, pads and rotors on the rear of my 300SE.

Used a lot of the advice on this forum to remember if I use enough WD40 and bang enough the rotor will come off, went ahead and got hoses too.

Everything was set to go but I have had two problems.
1. Went with reman calipers and while I thought my old ones were bendix it seems (from looking at the pics in fastlane) they were ATE type. I say this because the antirattle springs on my old cailpers were the flat metal kind. The ones I got from the local auto parts look like bendix from Fastlane and require a different antrattle spring. So I have ordered the kit and hope it is the right one.
Anyone run into this problem?

I cant find anyone who lists antirattle springs for sale.

2. Bleeding using the Mityvac (as others have said here) just doesnt seem to do the job. got some out of the line but no more. Yes I have looked at the MC and tried to make sure I had enough but not too much to get to the back compartment..not sure I have accomplished this or not.
So I will wait until another human being comes around to help bleed the old fashion way or rig up a power bleeder with one of the pump cannisters I have around.

Any tried and true method to get the rear lines filled with fluid?

Thanks

personally
 

i have never been successful with mitivac.

Follow up:

Filled MC reservoir to neck and it finally flowed to rear compartment. Expect bleeding to work better now.

Also found Brake hardware kits(with antirattle springs and pins) listed online at BeckArnley.com. Both types are there.

Thanks

Yep, that will nail you every time. Also, you don't get much bleeding done and that rear reservoir drops very fast, so be careful.

A little trick if you have no helper and no pressure bleeder:

Get a horseradish bottle (tall and thin).

Fill it 1/4 full with brake fluid.

Connect up a vacuum hose to the bleeder and run the hose into the bottle and down into the fluid.

Stand the bottle up near the wheel.

Crack the bleeder 1/2 turn........make sure the hose stays in place.

Get in and slowly press the pedal all the way down and release. Repeat 10X.

Close bleeder.........be careful to keep hose in place when you do this.

Remove hose from bleeder.

Refill reservoir.

Drain some fluid from horseradish bottle.

Repeat for second rear wheel.


I've done this procedure at least 10X and it works excellent.
