What have you done to your Tacoma today? 1st Gen Edition

Pretty sure @Blackdawg said that is typical but at this point I don't remember for sure. Did you two person bleed or just gravity? I like to two person bleed with a clear tube to make sure it is perfectly empty of air, but on my old Maxima I could just gravity bleed no issue, the Taco doesn't respond well to that.

 

Two person, with a clear tube. Started rear passenger, then driver rear, front passenger and finished driver front. Did that like 5 times.

 

Did you bleed the LSPV too, it is a high point in the system and has its own bleeder.

 

Question about this. Are there 2 of those, or just the one in the rear? And I didn't bleed the rear one - should I?

 

Only one and it's in the rear right above the rear axle on the driver side

 

Yeah I saw it when I was putting a longer brake line in. Noticed the bleeder, or what I thought was one. I'll have to bleed it.

 

I definitely didn’t bleed that, nor do I know what it is. What is that?

 

Here is a picture of it I took while installing a longer rear brake line. Did the Tundra mod. too. I didn't bleed the LSPV.

 

Yes, you will notice a slightly softer pedal after doing the brake upgrade. The pistons are larger in the Tundra calipers, therefore you need more fluid for a given stroke length (how far the brake pad moves). You didn't change the master cylinder, so you need to push the brake pedal further to push more fluid into the calipers.

Load Sensing Proportioning Valve - adjusts the braking force in the rear brakes depending on how much load you have in the bed of the truck. If you just changed the front brakes, and didn't allow any air to enter the brake lines (kept the MC full the whole time), then you don't need to bleed the LSPV.

 

Here's a picture of one on a pickup, I can't find a Tacoma one but they're similar enough. Sense the load in the bed to adjust braking power to the rear.

 

He bled his rears (didn't have to initially) so ya never know. Also did you ever fix your welder, I saw one on CL the other day and wanted to pick it up but I wondered what the verdict on yours was.

 

Loud or quiet whine? Like can you only really notice it if you listen for it. Mine whines a little bit from the clutch fork bearing and the input shaft makes some noise too. If it is really loud then I'm not too sure, failing bearing possibly. You can use a cup taped to the end of a screwdriver as a stethoscope to pinpoint noises.

 

Pretty loud, especially at height rpms. You definitely don’t have to try too hard to hear it.

 

Hmm the the W59 isn't typically very loud. I'd check all the fluids for proper amount and water before going further.

 

If you're interested, I've made a few of these as well. Have one now - https://www.tacomaworld.com/threads/1st-gen-bed-rack-ready-to-ship-have-it-for-christmas.522913/

 

Throw out bearing sounds like.

Out of curiousity...

show me a photo of the Booster and MC.

But yes, usually bigger brakes means softer pedal. That said, mine didn't really get that soft. At least not my stock MC. curious to see which one you have as you have the odd ball year 2004.

 

Nice. Are you planning on bedding them as well? Seemed to help the squishiness for me a bit (though, mine never felt that different than my Tacoma brakes, much to Monte's chagrin ).

 

All brakes, even OEM equip "should" be bedded. I'd read a couple tech documents on it, interesting stuff.

 

No idea really. Seemed a bit strange to me too, as I didn't do it when I bought the truck 17 years ago . I think the key bit is this... essentially, it just speeds up what normally happens in that first ~500 mile break in period for a new truck.

 

Every brake pad set I've bought has mentioned it, PowerStop likes to give a whole document on it. All you are doing is quickly getting to the point of most friction by using high speed to deposit material in the low spots and grind the high spots (these being very minor, we're talking measure with a needlepoint micrometer) as well as match the friction surface of the pad to the rotor. Friction increases the more surface are you can have meet another surface completely flat. The rest of the process is about not overheating the rotor, that's why you don't come to a full stop ever. You don't have to believe me though, go look it up if it is that interesting. Super easy to do and the idea behind it makes sense so there isn't much reason to contest it I'd think but if you find a tech document from a major manufacturer or brake supplier that says otherwise then it might get interesting to me too haha.
