Front brake caliper Question

[Bulli]

Last night i replaced my jeep's front brake caliper pistons. About 800km ago i replaced the sliding pins on the calipers becouse the dust seals was torn and resulted in the sliding pins seizing. The dust seals came with new sliding pins in a complete set from Crysler. (The pistons also came in complete set with dust seals and piston seal from Crysler. R167 each. Cheap, Dirt cheap...)

Now my problem is that after 800km (500miles) the bottom sliding pin with the rubber insert (wich i did grease when i assembled) refuses to move a inch. The top sliding pin without the rubber insert moves free.

Is this the way it is designed to work(i doubt) or do i buy two more top sliding pins to replace the bottom ones?

Would replace the lower ones also,or at least free them up.

But thats the thing, it was replaced. With new ones! From the agents.

did you use normal brake lube on the bottom slide pin or did you use silicone brake lube on it? the normal lube makes the rubber swell. even some that say "safe for use on rubber parts" will make them swell some as well.

I used the grease that came with the sliding pins.:freak3:

Hi Bulli,

Yes that is the way they are designed to work but the one with the rubber "seal" goes on the top not the bottom! It is a good tight squeeze to get the rubber sealed one in and out and they are a lot harder to manually slide in and out but that is the way they are. It is to do with a trailing edge and leading edge of the pads to make them wear evenly and not wear into a wedge shape. You won't have harmed anything and it is only a 10 minute job to swap them top to bottom. And yes use silicone grease on the pins. Hope that makes sense. Steve :smokin:

Left front brake clicking when braking at low speeds

I've have so many problems with my front brakes. Seems like I have to fix them every few months. One thing I learned is not to buy cheap pads. The backing plate came loose and jammed in the caliper.
Anyway, recently I kept hearing this clicking sound from the left front brake.
Only made the noise when I was braking at slows speeds, otherwise they worked fine. Finally got tired of the noise. Somewhere, someone said that I should replace the spring clips. So I bought new pads and a hardware kit.
Which included the clips, rubber boots, and the little rubber things that go on the upper slide pins. So I replaced everything. Cleaned up the rust where the clips go on with a wire wheel on a drill. Also cleaned up the pins good.
Put them all back together, making sure the pins were well greased, and moving freely. I won't know if the clicking sound is gone, until I drive it for a few days. Because I replaced the pads before, and the clicking sound came back after a few days.
But as I went to do the right brake, I noticed the old pad was worn uneven, like a wedge, as Steve mentioned...
I'm just hoping all is good this time, and the clicking sound is gone.
It was a constant clicking, not as I first hit the brakes.
I am so tired of fixing these brakes!
Oh, I once had a band new rotor crack, on another car. After only driving a mile or two. The work was done by a mechanic, so he replaced it the next day. I guess it was the cheap metal from China.
