Rear brake job question

Well I have tried this so there would be no damage to the hoses while resetting the caliper piston. I just use a tool, like a broom stick, to slightly hold the brake pedal down some. This should stop any flow of fluid back through the system. Then I open the bleeder valve, reset the piston and close the bleeder valve. Remove broom and repeat procedure for other calipers.

Of course add more DOT 4 brake fluid before you drive! ;-) Or you can flush your brake fluid, which would probably be a good thing too!

Is this a safe method?

Dennis,

I did mine a few weeks ago.

No need to open the bleed valve.

Just watch out in case the reservoir is already full, as you might spill some as its pushed back into the reservoir (I took some out using a syringe first)

Also you need to use a TOOL to reseat the rear pistons as they are a screw type not a push type (Front are regular push types). There are plenty of aftermarket tools that do this job.

I tried a few things but gave up as the piston was so tight.

I've read that it is a good idea to open the bleed valve on abs-equipped cars, as there's a *small* risk of damaging the pump with back pressure if you don't. Given the price of abs pumps, I wouldn't risk not opening the bleed valve if it was me. Never done it on an abs car though.

I heard the same - the only difference being that I heard the risk of damage was not "small" (!)
