Default Replacing rotors and pads **Question**

Did anyone replace pads and rotors and not bleed the ABS system?

It's time for breaks, I've always done them myself on other vehicles (honda, chevy; ford volkswagen...ect) and compressed the pistons with a tool, swapped breaks and went on my marry way. Any one else just replace pads, rotors, and hardware and stopped there? How did it work out? Can I carry on this way with a 2014 LWB 2WD and not worry not bleeding the breaks on this electronic abs pump?

First off, it's "brakes". And yes you can just do it as you have on other cars. Just did mine last week and all is well.

Just make sure you take the top off of the brake fluid resivour and put a squished paper towel right at the top to soak up the brake fluid that is pushed up from the calipers when you replace the pads. You'll need to push the pistons back into the caliper because over time they've pushed out to make up for brake pad wear.

I've replaced countless pads and rotors and never touched the fluid unless it was time to do so. You'll be fine

No need to bleed the brakes when doing such a brake job. But you do need to keep your eye on the master cylinder. The reason is you need to push the brake pistons back into the caliper to make room for the new (thicker) pads and rotors which obviously will cause the fluid level to rise in the MC. You don't want that corrosive stuff overflowing into the engine compartment. You'll probably need to remove some and then just top off the MC when finished. Easy peasy!

You could drain some of the fluid by opening the bleeder on the caliper but that can be risky as you don't want to introduce air into the system. If the fluid is dirty, or hasn't been flushed in the past couple of years, you can take it to the dealer or whomever for a flush and fresh fluid as you will need Techstream to do it yourself. That's what did I and it wasn't that expensive.

I installed all new rotors and pads in my 2007 a couple of years ago and had no issues at all. However, I recall a thread or two where the ignition was turned on or car started and brake pedal depressed (somewhere within the process, perhaps after old were removed and before the new were installed), and that caused all sorts of problems.

I would zero down and leave all valves open on this car, the fronts in theory do not need this but the rears would be best done this way.
