changed discs n pads now no brakes!

[sy84]

hi i have just changed the front and rear discs and pads on my vts now the brake pedel goes strait to the floor,i didnt take any of the brake pipes of so can't see that it would have air in the system.

What this man said. When fitting new pads/ discs you retract the pistons - a couple of pumps of the pedal and they should be touching the pads again.

i have pumped the pedal for ages still goes rite to the floor,was fine before i changed the discs n pads:wall:

You haven't opened the bleed nipple have you?

[sy84]

na i havent touched the bleed nipples,iv jst sat in the car again and pumped the pedal for ages then looked at all calipers and there is no sign of leaks,

Are the rear pads clipped into the pistons corrently? You need to wind the rears back in and then line the notch on the pad up with the piston so it slides into place.

[sy84]

i will take the pads out and double check,how would that cause the pedal to go strait to the floor tho?

[Liam_]

Not too sure bud. My thought was maybe a piston/ caliper is siezed. I'd double check the pads - see if the piston is making contact with the back of them and that the calipers can slide.

Everything look ok at the fluid reservoir under the bonnet?

[sy84]

will take a look in a min its strange coz they worked fine till i fitted the new discs n pads

[Liam_]

Probably makes no difference, but did you try pumping the pedal with the engine running?

[sy84]

yea tryed that aswell m8

Have you read the narrative in the Haynes Manual about the Saxo brake system?
I'm at work and dont have one at hand to reference.

[sy84]

no i havent got a haynes manual m8

you mite have F***ed the master cylinder. not sure if its common on saxo's but i can happen when u push the piston back the pressure of the brake fluid could have brokeededed a seal.
