BRAKE PROBLEMS HELP NEEDED

[Declan]

Just changed the brake pads on my 2006 defender 110 and bleed the brake lines but know the brake is hard at start up but then you can push it right thru to the ground,I have bleed it a couple of times and it seems like there is no air in the line can some please tell me what else could be wrong I was hoping to get away Easter but with the brakes this spongy I would not take it on the road as you have to pump to get brakes but it still goes to bottom point. any help would be appreciated.

Regards Declan

Why did you need to bleed the brakes ? Was there a problem or need ?

I would have thought that you would have just pushed the pitons back into the calipers.

It sounds like air in the system, but it could be in the abs unit.

A while back I lost all brake fluid when one brake line cut thru and the brake were spongy when I bleed it last time but not as much so I thought I would do the lot since I was putting new pads in.

I surgest you did not bleed the brakes right and need to do it again

All it can be if they worked before and now don't.

Start with the rears,it sometimes helps to back up a set of ramps and then go to the fronts,I pour the fluid through them and when convinced the air is gone do a slow pump closing the nipple before the peddle goes to the floor. Pat

Would also suggest re-bleed .

Use a vacuum or pressure bleeder, it's the only way I've ever got a pedal in a Defender. (and i still can't work out why)

[Declan]

Thanks for all the replies lads I will try a vacuum & pressure bleeder.

I reckon it's a stuffed master cylinder. The fact that it goes hard suggests that the air is out but when further pressure or peddle application is applied the fluid is bypassing the piston seal.

It is common practice to only apply half peddle stroke when bleeding a old system as the lower half of the master accumulates sediment, when full stroke is applied the sediment damages the seal.
