Brake Issue after changing pads?

[toolapcblack]

Hi All,

I have a Brake Issue after changing the front pads on my 2004 corolla verso D4D...i swapped the pads out the way i have always done, in fact it was a bit easier than most as on a focus a few times the pistons were corroded from being protruding out over a few years and were a bugger to get back in.

I removed the caliper bolts took out old pads, removed Master reservoir lid (placed a rag around) & wound the piston back with a G-Clamp and fitted the new pads. After this i pumped the brake a few times and went it rock solid so all good.  A while later when i started the car to move her i noticed the brakes had gone spongy pumped them and still the pedal keeps going to the floor... has pushing the fluid back damaged some seals or something? Or has air found its way in?

 

Thanks in advance J

Hopefully you just need to bleed them again, but it is possible - I've been told it's best to use a piece of wood or something big and flat to push back the caliper rather than pushing on the piston directly as they can be damaged or the rubber bit pinched/turned inside out.

I would bleed them until you see the new clean fluid coming through and see how they feel after that.

It shouldn't be possible to damage the seals just by pushing the pistons back.
