front callipers.

[PPP38vouge]

Hi everyone,
just replaced front discs and pads and now have discovered that my drivers side calliper is sticking, have orderd 2 new callipers, may as well do both, only cost £35 each including delivery, I plan to clamp hose above calliper then swap them out, my question is should I depresurise system first before removing calliper? have done this on other vehicles but never on one of these beasts.
thanks in advance.
Paul.

As long as its clamped firm should be fine but if it makes you feel better cant see any harm in deprsurising

No need to. As long as brake pedal is not pressed whilst pipes are disconnected.

Excellent, thanks very much.

I wonder if you could bleed the new calipers by leaving the clamps on brake lines of the fitted calipers, open the bleed nipples with a one way valve on each. And then give a quick press of the brake pedal - checking the level between each press. Surely the fluid under pressure would find its way past the clamps but they would hold well enough to stop the back-flow of air?

Not suggesting you should bleed like this - just thinking and typing at the same time - bad idea I know!

you remove clamp ,open nipple and then press pedal then tighten nipple before letting pedal up then repeat

I know the standard way of bleeding brakes James, the problem is some air always finds its way up the pipe when you release the clamp. I'm wondering if you could use the clamp to stop any air in the new caliper ever finding its way into the system. ie would a typical brake hose clamp allow fluid under pressure past.

it doesnt go far if you bleed just after removing clamp and dont leave it overnight ,i never have to bleed the system to do a caliper

Hi, yes that's how I planned on bleeding new callipers, how many pumps do you think it will require? I was thinking 3 or 4.

 

[gfromleeds]

3-4 sounds about right

Thank you.

2 people, one on the pedal, one on the nipple with the clear tube, bleed fluid till its clear of any bubbles, tighten nipple and test firmness of pedal, signs of any leaks
