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?

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

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%.

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 .

Cheers guys, ill put some miles on um and re bleed them during the week, :)

Had the same thing with mine. All the brakes were new/rebuilt (rebuilt calipers, new discs, new pads, new pipes and hoses, etc) and the pedal wasn't great at first. By the time we got to Scotland it was much better!! Now it's a good pedal feel.
