So are you, you Muppet, you didn't see that either!



Like this .....

Thanks for that Simon but I still cant see how the system wont bleed. I checked the pipe and caliper movement during fitting and there was virtually none although this will bring it to nil

When you say it wouldn't blead, what do you mean?
Did you just have a soft pedal?
Sure it's not just the pads that have not been bedded in?

No. Basically the first application of the pedal went straight to the floor with no application of the pads and the second was rock hard and the brakes were fine. Ya cant drive like that !!!
I have reverted to the standard discs and calipers with new pads and the brakes have never been better so the actual brake circuit is fine. It was odd that I had to file a little off the caliper to get the wheel to fit without rubbing. Mefro or Ronal!

OK. Just reassembled the SA brake kit onto the van again with the springs on the way Simon suggested and guess what ......

No difference!

I wrote to Busschmiede and he doesn't want to know even though the parts are brand new and only covered a few meters driving around the house! He says I have fitted them wrong which is odd as there is only one way the disc can be fitted, there is only one way the carrier can be fitted without fouling the disc and there is only one way the caliper can be fitted to the carrier!

Not happy with Busschmiede. Will have to say a few words at Mammutpark.

have you tried disabling on of the brakes to see if you can tie it down to which side is causing the problem.
usually by clamping the flexies, but I see you have bradied hoses so that won't work!

So, with standard brakes it's fine.
With SA fronts it isn't.
Rear brakes I presume are adjusted okay, if they werent then you would have a similar problem whichever brakes were fitted.
You are 100% sure they are bled up right? have you tried bleeding the caliper without it being attached? maybe some air trapped that won't naturally find it's way to the top, like the bleed nipple isn't at the top of the cavity in the caliper?
What happens on the first press, can you see the pistons moving out at all?
Sometimes you get it when the caliper seal is dry (not the dust cover the actual piston seal) and rather than the piston slide through the it pulls the seal a bit, meaning that when you release it, it returns more than it should, meaning that when you come to press again the piston has to travel further than it should do.

I would try bleeding it with one of the pads removed, or something thinner in there just to get the piston going, or squirt some free-ing oil behind the dust seal so that if it does move that it is lubed (maybe wrong type of oil but in fairness it's not going to make knob all difference.

Thanks for you input Simon. TBH at this point the van is spot on and ready for the trip to Mammutpark so I wont do anything until I get home from there. The piston does move but you are correct in suggesting bleeding under different conditions - off the carrier and with thinner pads etc - as it could make a difference. Im going to bring the calipers to Germany as there is still the other issue of having to grind a little off the caliper to prevent the wheels from rubbing. Id like to compare them with other SA calipers / dump them on Busschmiede's desk!
