Hi all, just stripped & rebuilt front & rear calipers on L3 model. What's the best approach on bleeding front set to get a decent result please as currently lever is like squeezing a jelly & frankly no bloody use
Any help greatly received, thanks in advance

Full left lock, this keeps the m/c raised and at an angle to get all the air out.

then pump until hard, keep lever pressed, loosen off nipple, tighten nipple.

rinse and repeat.

Thanks cansa, problem is this is how it was set up & tried for approx 1.5hrs in various approaches just its not responding in the least. Resivior is at dropping level at all thinking possible master cylinder fault

You need to use a vacuum bleeder, or reverse bleeding where you inject liquid from the nipple, into the calliper, up the line, past the MC into the reservoir

I've never used a vacuum bleeder or reverse bleeding.

Never had a problem.

Imo I've found that the traditional method works for most but a few have had to resort to vacuum bleeding.

I always had great results with the normal way but got a vacuum bleeder from Santa one year so have always just used it

Thanks all for the input, going to opt for the pressure bleeder & not beat around the bush with it.
