Spongey brakes

burgerman:
 Hi all,
  After finding a brake caliper piston that had seized and quite unwiling to free off, i brought 2 new calipers from paddocks, fitted um up no problems, used new pads ect, bled through straight away, lovely job,




BUT  !    on road test the pedal feels "wooly" it doesnt seem to me like air in the system, as i can get a hard pedal straight away and doesnt creep down with constant pressure,  SO - re bled the brakes thoroughly ( used over half a litre of fluid) no air coming through, covered 50 miles or so now still no better, I can only guess that could my brake fluid i used be no good/absorbed water ?? its kept in my garage in its original bottle, it was opened although did have a cap on it, not sure how old it is  :-k possibly 2 years?? def not antique though  :lol:  

  Weather permitting ill slide out there in the morning, kidnap my neighbour again to assist in pedal duties and buy some new sealed fluid, any further tips/thoughts folks   :-k  Many thanks

 P.S its a 51 plate TD5

you havent got any play in any of your wheel bearings have you?

burgerman:
No matey, thats one thing i adjusted whilst i was in there, good tip though  :)

Range Rover Blues:
The callipers are new and because the seal act as the "return spring" you will be getting more return from the new callipers, they wil be like that for a while.  I also find that I need to use a new calliper for a whiule before I can bleed it 100%.

lurch_917:
as rr blues says some times you have to run a new caliper for a wile , before you can get a affective bleed due to pockets of traped air in the corners of the casting . also try bleeding it with the engine running ie servo working .
