Hi all.....
I recently had the dreaded 'piston seize' on my 4 pots,I replaced them with a pair of 'wrx-pro' calipers.....
After changing them,bleeding them (every way known possible) the brake pedal was horrendous...after re-bleeding them it was no better..
The first press of the pedal almost went to the floor then they would be rock hard....I noticed the near side pads rattling in the caliper.....
I bought a refurb kit and rebuilt my old 4 pots.....refitted and bled and it's exactly the same......

Any ideas??

Cheers

 

Before someone else asks,have you got the bleed nipples at the top and are all of the pistons moving when the brake pedal is pressed.

 

Yes....the bleed Nipples are at the top.....
The pedal feels the same with either set on......

 

when you say bleeding them every way known possible ??

 

Gravity bled,vacuum bled,pressure bled...(pump and hold and open bleed nipple press pedal down,close nipple)

Get the idea......

 

PMD you

 

But are all of the pistons coming out when you press the brake pedal.

 

That's one thing I'll check

 

Any luck.

 

Yes,after receiving a pm from Nikon man and following his advice I now have brakes again......
Thanks for the advice people..

And Nikon man.thanks again..

 

So are you going to keep the solution secret.

 

i will put a write up on how to bleed the brakes in the technical section

 

Great stuff.
