changing out my brake pads in the front. Put one pad in but i wasent paying attention and the two pistons on the other side of the rotor popped out....how can i get the piston back in there??? Crap...what a day...

 

completely out or just pushed out a bit? if so, just use leverage and push them back in without putting direct pressure on the pistons

 

i got it!!!! replace al four front pads...now my ebc light and couple other lights are off...what gives??????

 

the brakes are electronic, alot of times when you do push the pistons back in, the pressure/fluid level in the electronic brake actuator is not within range of what it was when the car was shut off; that will cause caliper codes. I have not tried using a regular scan tool to clear the codes, but all you have to do is clear the codes, it's totally normal. Maybe even take it to a lexus dealership, they might just clear it for you if you tell them you did the brakes yourself. They should know better that sometimes a brake job will cause those lights to come on.

 

^ thx for the info. i just wondering if this is like a hit or miss.. wouldn't stepping on the brake pedal release the fluid back?

 

wow...thanx for the info....i'm resetting the battery as i type..let it sit there for a few hours. I figure i would give it a try, before i take it to the dealership. You guys are so much help. thank you.

 

Another thing to try for you DIYers is, open up the bleeder screw before pushing the pistons back in. Of course place a vacuum hose or some sort and drain the fluid back into a bottle. This will prevent the fluid from going back upstream and instead, go into the bottle.

 

Not so much of a good idea, there is a pain in the *** bleeding procedure on our cars with electronic brakes. If you happen to get air in them, you'll be paying for bleeding brakes. Brakes can only be properly bled with the Lexus scantool. You have to push air out electronically with the brake actuator from every corner. The procedure up there is good for cars without electronic brakes.

 

Great advice, happened to me once, cost me a $100 at the stealership ! good luck

 

If done properly, you won't be letting any air in. The only thing that's occuing is the release of used fluid in the bores of the calipers.

 

agree, you just need to know how to do it right on cars with EBC. my ls460l we changed the brakes out to brembo in my garage and bled the whole system with no issue. the idea is to not let the computer know you are bleeding the brakes

 

The front is very easy. Just take caliper off, use C clamp to depress while old brake pads are still in place, then change. I've done so twice on my 2008 GS 350 AWD. I use the best after market pads with lifetime warranty from AutoZone. No problems in two years.

 

Good to know as I'm changing out front and rears this weekend. Using wagner cermanics and having the rotors turned at kragen.... thanks

 

just one more thing to have stored to memory for dealing with our precious cars
