Brakes

[sprinter119]

Just wanted to get some other opinions from the MSPROTEGE group. I did some research(RTM) and I am fairly certain my front right caliper is seized. When I hit the brakes real hard you can smell and the rotor is always hot. When I am on a slight incline the car doesnt roll back like it should. I am now going to replace both Calipers, Rotor, and brakes since the car now has 90K. Where can I buy some good/reasonable parts OE or Aftermarket? Thanks for the help everyone.

Go to www.TireRack.com, they have better parts at cheaper prices (even I was surprised).

Though I have never done it on a seized caliper, I think it's logical that depending on why it is seized, you could rebuild it at a fraction of the cost of a new one. If the piston seal went bad, and dirt got in there causing it to seize, then I would think you could rebuild it...

At the very least, you could take it apart and check if it appears rebuildable.

They don't sell calipers tho, and if you get all your stuff at one place, you'll save a lot on shipping.

RockAuto.com FTW

Thanks guys I have never done a caliper rebuild. I was just going to replace everything since I am 10k away from 100000 miles.

A siezed caliper is not a good candidate for rebuild. Only a leaking one is good for a re-seal.

Replace with OEM calipers and rotors and upgrade to Hawk pads.

Do a real good bleed to get that burnt fluid out. Remember to keep topping off the reservoir as you do it...

Pfunk do you know if there is a how to on here for a caliper change? I know there is for the pads if theres not I will just have a MD person teach so I will now for next time.

The link I posted was part of a brake how-to. In the top right corner when you are viewing it, there is a link to go to the original thread.

chances are good that the caliper is not seized, but the slider pins just need to be cleaned and lubricated. mazda doesnt like to lube them up enough from the factory.

I might need to do the same. Hey Chris...let me know when you're doing yours man!!!

I can't help you/teach you right now (I am serving in Iraq)

Well I know my brakes are sticking. About 5 years ago someone poured tranny fluid in the master cylinder instead of brake fluid (!*&!@#@). After the front caliper clamped down on the rotor about 4 days later we drained the lines and flushed them with some kinda alcohol (can't remember what kind), and replaced the front pads and rotors all around. I think one or two calipers are sticking again, so this time I'm gonna do it right. I replaced the master cylinder...should I replace the brake lines?!

You should just inspect the calipers and clean/lube the sliding pins first. Once you flushed and refilled/bled the system - it would not cause the calipers to hang up again later.
