Braking Issues... Some Quick Advice?

[Brian757]

Alright. So I've got ~141,000 miles on my truck now, and I'm starting to have braking issues.

Current setup:

• My front calipers are the 13WLs with 231mm rotors, which were done about 5-7,000 miles ago.
• The rear has factory drums with new pads.

Symptoms:

• When braking hard, I hear popping from the front/rear occasionally
• I constantly bleed my brakes because air gets in
• When checking my rear brakes a few weeks ago, the rear driver side adjusting pin was out of its groove (I dont know the technical term)
• I have the goose sound coming from my dash periodically

I am guessing that it's my master cylinder, but I'm uncertain. Where should I start? FYI - I'm not losing brake fluid.

I guess it's worth saying that I don't have issues stopping, but I can hear a popping/scraping sound and it vibrates the brake pedal when I hear it. I can say that my pedal feels mushy on occasion. I was going to wait for it to get worse so I can easily diagnose it, but I don't want to find out the issue going 70 mph on the interstate.

Are the rear brake shoes TOYOTA? If not, I suspect the length/dimensions of the metal plate (where the brake shoe material is bonded) on the rear brake shoes.

Do you have all the returning springs inside the drum properly fixed? did you reface the rear drums? if not, don't do it. Many machine shops don't know how it right. After refacing the rear drums I started feeling pulses to my leg when I apply brake at low speeds.

For 140 K miles, your M/C is brand new. I have 200K and still like new. the only way you can destroy a toyota brake master cylinder is by adding a differently rated brake fluid.

I believe your problem is with the rear brake's and not the front.

Great! I will look into it.

I believe I fixed the rear brakes when I reinstalled it but when I was bleeding the brakes after doing them, I heard a LOUD ping in the rear end like it popped back out. And no, unfortunately the brakes are AdvanceAuto crap. I will order Toyota brakes and install them. Thanks again! Should I buy new Toyota drums as well?
