using calipers upside down, and how to bleed them?!

i know this has been covered before, but can never find what i'm after on forum search.

as it is, using the brake calipers the correct way up, bleed screw at the top, the plastic plug is got in the brake fluid inlet port just now, bangs against the bottom wishbone. certainly no space to safely install flexi brake lines with any kind of end fitting.

flipped the calipers over, and they fit perfect, but the bleed screw is at the bottom.

its been said before (i think) that they'll happily work upside down, but how would you bleed the brakes? surely the disc has to be in place for something to clamp against when getting the air out?

an all calipers/pads work upside down, is there something i should check?

i do intend changing the standard bedofrd midi calipers (as using midi uprights) to wilwood ones eventually, but this means a whole lot more money for calipers, disks, bells... etc

you could try taking them off putting something in to hold the pistons open(block of wood)
bleed them the right way up then put them back on?

Just whip them off, insert a piece of wood to take up the space of the disc, and bleed them the right way up.

Rats - Martin beat me to it

cheers guys, just what i wanted to hear! (or read...)

i was thinking that (or maybe a similarly thick peice of metal)

can anyone think of any reason why they wouldn't work upside down?

I do plan to use flexi brake pipe throughout, so taking them off to bleed them would not be a problem

What calipers are they? why cant you swap them from side to side?

...what I was going to say. That way, the bleed nipple would still be the right way up, just on the leading edge instead of the trailing edge (or vice versa)

Don't find a piece of wood to hold them apart. just move them round the disc with the pads in place and bleed them like that. I do.

u can't bleed them upsidedown cause the air will allways go to the top as it lighter than the fluid.

Think what was suggested is that they are rotated around the disc until the were the right way up and then bled.

I have the same problem and I can't just swop the calipers from side to side as they are directional.... I planned to move the bleed valves on mine But I guess I could bleed them right way up and the refit them to the car.

The handy thing about most aftermarket calipers is that they have bleed nipples at both ends so the problem doesn't arise.

You shouldn't swap calipers side to side as I believe most are designed with the piston(s) slightly off-centre to counteract the effect of the direction the disc moves through the pads. Using calipers like this the wrong way round would cause rapid uneven pad wear.

I did wonder about these things being directional. I noticed Wilwood brake discs seem to be left hand and right hand. Is there any way to check if they are directional? and how badly would the wear be affected?

Razman, i do plan of getting proper Wilwood calipers at some point, but not until after the build, maybe at the point when brake pads/discs need to be replaced. can't afford new calipers just now, thats money i should be spending on the engine at the moment hmm, or the back brakes, as i have nothing done there yet
