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 finally got somewhere, NIPPARTS brake pads are ****E!!! and i bet the discs will turn out that way as well.

no matter what i tried i couldn't get the outside pad to make full contact with the discs, cleaned everything i could, pistons and sliders both moving fine so no seizing, tried filing some meat of the pad but that didn't help, the pad was sitting at an angle and i think it was the back plate that was slightly out, bit the bullet and bought some quality blueprint pads and problem solved, just comparing the 2 makes is like night and day, you just have to look at the blueprints to see they are in a different league to nipparts quality wise.

buy cheap buy twice

going to replace the fronts with blueprints once the mot is done and i get paid, just don't trust them now.

when i had the last Celica i wouldn't have thought of putting cheaper brakes on but with a house and wife to be now im not allowed to spend what i used to , so, it wasn't my fault it was Jans. Always blame the woman :lol:
