Replaced my nans brake pads on her 1.2 8v 5-door B and after wards the pedal seemed to have a lot more travel. It's apparently getting worse now. Fluid obviously expanded and I've drained it out so it was the same level as it was before, not touched anything to do with bleeding etc.
Why are they so shit? It was fine before I changed the pads

Yer, it was getting better, to an acceptable level, but now I've been told the pedal is travelling further and further... Bit worrying! Fluid level is the same so wtf?

Even though it was fine before the pads were changed? I can't work out how/why it'd change anything regarding bleeding but will give it a go, can't not help I gusss

You fitted new pads but didn't bleed the brakes afterwards?

Why would you need to bleed the brakes after fitting new brake pads ?

Ive never had to bleed brakes after fitting pads.Why would you??
But if you have drained fluid out, and refilled it, then you will need to bleed them.

^ This....
Dont think it matters with the B's but i work in a dealership and when i started as an apprentice years ago i got told and know a few people who work in garages too etc who say the same, on the newer vauxhalls your supposed to crack the bleed nipple open before you push the caliper piston back otherwise you get this sympton after as its the seals flipped around in the master cylinder  lol
probably not this like just an idea though

I've always bled them myself.
It's worth a check anyway.
I think he means he took fluid out of the reservoir when the caliper pistons were retarded to accept the new pads. In which case you may need to add more fluid when they bed in.

It could be that the pistons had corroded and now that you've pushed them back into the bores they are leaking.

you shouldnt need to bleed just after doing pads, but if its spongy sounds like it needs doing, how old is the fluid? it absorbs water over time and this can cause this effect

Yeah I absorbed some fluid into a rag. The fluid level is the same as it was before I did the pads.

Makes sense, they were hard getting them back, proper had to force them. Would this mean a new M/C?

If that's the case you would need calipers not a new MC.

nan said if she pumps pedal the pedal goes more firm, does that mean the m/c is ok?

Just get your nan a set of Alpinestars boots, she can open the door and stop with her feet or dab and turn to avoid the VOSA stops.
