new brakes are crap, Help Options

[kevstir]

Hi guys

My MOT runs out on fri (yearly inspection in the UK) , i knew the brakes needed done so bought front and rear discs and pads, now the brakes were working fine but after replacing them last night they are now poo, they feel a tad spongy and when i got back from the test drive both fronts were smoking.

Below are pictures of the inside of the old discs, as you can see they are a tad rusty where they shouldn't be , is this a sign of seized pistons?? the sliders were all free and the pistons did go back in all be it not so easy (only had a screw driver).

drivers front



passenger front



all 4



this is how the new disks, as you can see the rears arent doing much and the 1 front discs is still score free near the hub

ns rear



os rear



os front



can i really have 4 seized callipers?? they worked fine before i changed the discs

or could it be that i haven't pushed the pistons on the callipers back far enough, if so what size of g clamp do i need to buy??

the front pads all had 2 anti squeal pads each and the rear had 1 per pad, my last celica never had any and never squealed.

im just a tad stumped as i did this with my last celica (a few times) without any trouble..

so HELP lol

well today i took the anti squeal pads off (completely) and cleaned every bit of the brake callipers and carriers , even took out the bits that the pads sit in and gave them a good going over, was surprised at the amount of crap i was able to clean off, put everything back on and there was an instant improvement, took the car out and the brakes were loads better, better than the were with the old brakes.

i still have a little prob though , the outside rear pads are still not making full contact with the discs (inside pads are fine, see pics) the callipers aren't seized as the wheels spin freely and got Jan to sit in the car and slowly apply the brake while i spun the rear wheels, and they don't get very hot after a drive so no dragging, is this just a case of the rears needing a bit of time to wear in as they don't do much of the braking??
