Loud "click" sound from passenger wheel area when braking, rattling noise

I'm bringing my truck into the shop this week for maintenance and am going to ask about this, but thought I'd ask here as well.

Approximately every other time I apply my brakes at low speed, there is a loud single "click" noise; I assume this is just the pad shifting and is normal when going from Drive to Reverse, as that's when I've always heard it. However, it's been upping in frequency during my drives and I've noticed a metal rattle noise from the same area when I go over bumps. Sometimes the rattle will sound similar to this click.

Thoughts? Loose pads? Loose caliper?

Thanks!

 

I have this and I believe it's call brake slap. Here's something I found back in the 2nd gen forum a while ago:
A "clunk" when starting or stopping just after applying or letting off the brakes. Caused because the pads"float" within the caliper and will knock on either side.

It's harmless but slightly annoying if you don't know what it is. I don't need new pads but was going to service the front brakes soon. You can shim them and/or add an additional spring that should also reduce the behavior. I've been accepting it ... They say that's the first step.

 

Check seat bolts too

 

Mechanic couldn’t hear the rattling, but I believe it is as you describe. Found that thread as well.

He did tell me my pads are down to 3mm (31,500 miles) and I opted not to change them just yet...since working from home I barely drive the thing anymore (only 3,000 miles since March). Can probably get 5 more months out of em before they need changing...then lease is up in March.

 

If your caliper bolts are loose, if you brake in drive, the caliper bracket will lean forward and hit the rotor. If you brake in reverse, it will lean backwards hitting the rotor. The brake pads that come on Tacomas have spring hardware that make them float above the rotor but if the hardware is broken or missing, then you would hear a click or metal slap sound when you brake. If you’re getting brake work done, make sure the hardware is cleaned and pads lubricated.

 

I had this.
Replaced my brake pads recently because it was time. Sound is completely gone.
The metal rattle could be your struts.
My truck is a 2016 and I occasionally hear the click/clunk going over speed bumps so I think it's my shocks/strut wear.
PS i have a shit ton of miles on my truck because I drive nearly an hour each way to work. Over 100k.

 

Thanks for the insight! Some stuff I’ve just got my fingers crossed until lease end. Have had a lot of issues with the rear brakes on this truck (see post history, had whole axle replaced) that I’ve just accepted there’s quirky shit that goes on with it.

It’s been quite enjoyable watching the days and months go by on mine with barely a tick on the odometer. My 35 mile commute was an hour or more just like yours...I feel for you.

 

Just had a thought...does anyone know what the minimum pad thickness is for passing inspection in NYS (or your state, just curious for reference). Can’t find much specifics online. Basically, I’m thinking my inspection is in January, 2021. Lease is up in March,2021. Averaging 3,000 miles every 5 months since the COVID work from home routine, I feel like I can still drive these puppies down to 2mm or so without issues.

Just trying to avoid spending money when my brakes are working fine. Had 46,000 miles on my Jeep and never had to change pads prior to lease turn in, so hoping for the same here
