2015 Tacoma TRD Sport Brake Bleeding....??

I've been searching and haven't found an answer I'm confident with. I'll be changing front pads out shortly and want to become prepared. It's my understanding that when you compress the caliper pistons, you need to open the bleeder. If any air enters the system, then bleeding is required. I'm no stranger to brake bleeding (I use a Motive pressure bleeder) but I've never done it to an ABS system. To complicate matters, I'm guessing I have a vac assisted brake booster (it's pouring outside now otherwise I'd run out and lift the hood) instead of the hydraulic/electric booster.

Can someone point me in the right direction? I'm hoping that I can use the pressure bleeder providing I can get the correct adapter for the Tacoma from Motive........

 

You don't have to open the bleeder to change out just the pads, just take the cap off the master cylinder when you compress the old pads back into the caliper

 

Thanks!

 

This is true, you can do it that way. Just make sure that the reservoir doesn't overflow when pushing the fluid back.

I wouldn't recommend it, as you should at least flush some of the old fluid out to reduce moisture and contamination.

 

I just did it this weekend. Slightly open the bleeder and use a spreader to push the pistons back in. As the pistons approach the seated position, be ready to close the bleeder. With one last push to seat all four pistons and while brake fluid is still coming out, close the bleeder. It's much better to dump the fluid from the calipers than pushing it back into the braking system, if you can avoid it. Once you reinstall the the pads, crack the bleeder and let it gravity bleed for a five or so seconds, close it and job done.

As long as you don't go crazy by allowing the pistons to reverse direction, while ensuring brake fluid is coming out, air is going to have a hard time getting in. Been doing this for years with no issues. My 2015 DCSB 4x4 TRD Off Road has a nice firm pedal after my brake job this past weekend.

When you're letting it gravity bleed, I'm assuming that you have the cap off of the master cylinder to allow the fluid to drop (picture water bottle upside down with a hole punched in it)? If it's just dripping fluid for a few seconds, isn't there a chance that air can get into the system (upside down water bottle without vent hole)?

I do understand its a closed system and in theory shouldn't let air in, but that's not always the case.

 

I've had no issue with the process I've mentioned.

 

I’ve used the harbor freight vacuum bleeder that hooks up to the compressor. Works well for the Taco and Gx470

 

If you have a pressure bleeder and know how to use it then great!

Don't worry about the ABS, it will flush out just like a non-ABS system
