Is there a proper way to spread the brake calipers when changing pads?
I assume the rears can be opened up with the adjustment screws. How does one spread the front calipers? Do I use something like a paint stick and make sure there is room in reservoir? Is it okay to push fluid backwards through the master cylinder? |

How does one spread the front calipers? Do I use something like a paint stick and make sure there is room in reservoir? Is it okay to push fluid backwards through the master cylinder? Since I don't do it often, I use a large C-clamp to push the piston back into the caliper. Have to do each side separately. You do NOT want to use the adjusting screws on the rears to pull them back, they were not designed for that. Back them out a bit, push the pistons in until they stop, back the screws out more, repeat... A small piece of wood with a cut out hole for the screw protects it from the clamp. Yes, make sure the reservoir has room, brake fluid is not friendly to paint. Or open the bleed screw a little do a mini-flush. |

[/quote] So it is safe just to push the front pistons all the way back, but the rears have to be pushed to the adjustment screw limit a little bit at a time? Is it okay to just open the bleeder instead of "emptying" the reservoir? I have speed bleeders. |
