Anyway today decided to regrease everything etc and was checking the caliper piston movement and went a tad too far and popped one piston out. Popped it back in, put all the calipers back on and went to bleed the system.

It won't bleed! Pumping the brakes builds no pressure in the front system and is passing no fluid at all.

So not kean on trying to ride it anywhere on only a rear brake so need to find a mechanic that can come and have a look. They usually have the little tricks to fix these things that mear mortals stumble on :)

if the pistons slide easily in the bores all it should need is a good bleed.

Start by bleeding the mastercylinder, take off brake hose at M/C and bleed,
then reinstall hose to M/c and remove hose from caliper and bleed that
and reinstall. then finally bleed the whole system.


or reverse bleed with a syringe thru the caliper

Without reading the whole thread. Pop down the boat shop on central park drive and grab a syringe and a length of plastic tube. Fill the syringe with brake fluid, crack the farthest bleed nipple and push the fluid up from the calliper to the master cylinder - pushing the air ahead of it.

Or you can come and locate the same stuff in my garage - trust me, it's easier to buy it.

You will still need to bleed the system, but that should get you started.

Hadn't thought of using a syringe. Will grab one tomorrow.

So effectively there just way to much air in the system is the problem?

Air bubbles don't like to flow through oil that quickly, that's why when you 'bleed' the system you push the bubbles out the bottom with excess fluid. Using a syringe and pushing the fluid up the the line should work, if it doesn't then you know you've probably screwed something up.

You guys rock....all fixed

Pushed fluid through from nipple on both sides then did a standard bleed to make sure.

Now can go to mechanics and show them the stuff up installing my pads tomorrow :)

Good one! Next time you will able to do your own brake pads! :niceone:

Make sure the mounting bolts are snugged down firm, then then tightened about 1/8 of a turn ish. Thats a little harder to describe than than it is to demonstrate. Basically you want just a little stretch pulled in the bolts. A LITTLE, thanks.. don't deform anything. ;)
