New front pads smoking

[jjaynes]

I tried to put new pads on the stock disc brakes on my 93 festiva. Don't understand why the front pad is so tight in the caliper. It's contacting the rotor and when I test drive I could tell as smoke was rolling everywhere. The back pad is fine. Not sure I understand what's going on. I am running the new rear pads (ones that actually contact the cylinder) and the old, half-worn front pads.
Thanks.

Did you clean everything out with brake cleaner and then use a healthy dose of slide pin lube or anti-sieze on the slide pins?

What brand pads?
Did they come with new hardware? As in the metal clips they slide on on the caliper?
Do your caliper slider bushings move very freely? They need to be greased periodically.
The bolts that go through these bushings. If they get siezed the outer pad doesnt move. So normally your outer pad just stops working and only your inner pad does the work. But if you put new rhicker pads on and they are still stuck the outers will smoke.

Ahhhhh this makes sense...what is the bushings seals are rotted?

Your seals are rotted? Then water gets in and rusts everything and it all siezes. www.rockauto.com has new bolts, bushings and seals cheap.

i speak from painful experience. this is an annual ritual in rustburgh. it is amazing that a rubber sleeve filled with grease can still allow the bolt pins to seize. go a step further. when you have the boots out of the bores run an appropriate sized hone through them to remove corrosion and rust. this will also make it easier to fit the 1 pc boot back in. otherwise it seems very hard to keep that boot from elongating (stretching) when you push the pin back through it. i always wished someone would sell or machine these pins out of stainless.

Got it fixed. Thanks for all the input.
