Hey all,
Update here.
As noted above, I temporized for the winter with the new Bosch ceramic pads up-front.
But, alongside that I got a good deal on OEM parts for new calipers and rotors all-around, including the upgrade to the GX460 calipers in front. Went with EBC Green, and stainless braided lines and some Stop-Tech fluid from Summit Racing (consistently reliable source for me...)
Found a local shop to do it, very reasonable cost, too; as I don't have a great jacking/working space and I'd already done these jobs before (and dragged my kids through parts of them for teaching
, so less novelty value).
Two things:
1. They didn't feel as tight as expected when done, and got quite spongy over several weeks. I didn't drive the car for a block of time so was shocked when I jumped back in it. Figured out how to bleed them, the little pump requiring the key on was new to me, and they were *solid* right afterward. 1.5 weeks later, they feel somewhat soft again to me.
Questions:
- how likely an explanation is it that there are some little bubbles in the new calipers that are working themselves slowly out?
- or that I allowed some air to creep in figuring out the pump process (I first tried bleeding these like old brakes without any electrical components)?
Other possibilities would be a subtle leak in one of the connections, perhaps with the new lines, etc.
The master cylinder wasn't touched and I would assume the guy who did this, who isn't a new mechanic and knows Toyotas, wouldn't have introduced air up top.
I'm contemplating biting the bullet and getting a tool that can trigger the ABS and bleed process from above, just to make sure the top is cleared. I got the ABS to fire once or twice during my test drive without an obvious change in feel. So I don't think that's it, just being compulsive.
Might also take it back to him and ask him to figure it out, easier to inspect on the lift, etc.
2. I now have old calipers all-around for the GX-470. The shop I bought from is 300 miles away and no core charge was listed, so I'm guessing there isn't much value that way. These are likely scrap unless someone can use them. If they're of value to anyone here, I'd be willing to do the work of boxing them up and sending for just the cost of shipping, just so they'd be useful. Figured I would ask!
Thanks,
D
