Brake system flush (1 Viewer)

[cumminsBase]

Did anyone figure out if Techstream could be used to actuate the ABS pump to flush/bleed the brakes and pump?

I did not find anywhere in Techstream an option to bleed the brakes.
Yet I did buy the OBDII computer which has specifically the option to activate each corner's circuit.

When you tell the OBDII computer to perform "system cycle left front" you hear the brake's pump for a couple of seconds, and a healthy amount of brake fluid flows out the bleeder screws.

I did this for all four corners, in addition to the bleeder screw plus vacuum pump.

When you say "OBD-II" computer are you referring to the Toyota handheld tool?

I plan on doing this in the next month. Just checked mine. Reservoir looks dark and fluid is a dark green tint.

I have unsuccessfully flushed before using a couple of gizmos so today went back to basics and the result is the return of a confident brake feel and performance.
1) key off.
2)press pedal till it bottoms out. This is a good time to remove much of the reservoir fluid and put fresh.
3)turn key on without engine running. Took about 30 sec booster running.
4)attach a hose to FR and 10mm ready.
5) respectfully ask wife to watch her netflix on the driver seay.
6)three pump on hold PLEASE.
7)release 10mm and wayched air/ fluid out then close the valve.
8)ask boss to release pedal and repeat 3 pump and hold. Repeated about 5 times then clear fluid.
9)check reservoir level and fill as necessary.
10)repeat FL, RR, RL.
11) quick drive and activate ABS few times.
12)return and ask boss for her foot again and repeat.
13)yest drive and grin over a work well done.
14) clean up and check fluid lebel.
15) bourbon treat to myself.
I did use the fitting that came with some kit i tried but would work without.

Every step of the task makes perfect sense, and will techstream ABS.... shes on stands, motive bleeder in hand with power probe adapter waiting to be put on, yet .........

After what seems like three 1/4 days of reading every flush thread, and being ocd/anal to using Toyota fluids and filters, and since my amazon order from a dealer produced the older style label (as shown in post#32) with a date code of 200036. I am left thinking those bottles may be as old as my 2000 LX! What a sh!t show this has been to just try and get what i need delivered to me as opposed to having to "go out". I am left to ask:

Do I go to the parts counter at Toyota and get 6-12oz bottles Dot 3?
or are they going to look at me sideways and say we only have Dot 5 now? (Clearly I dont "get it"!).

or
Prestone Dot 3 delivered from O'Reilly (2- 32oz bottles) (pains me a bit, hoping for sanity check here)
or
should i be looking at dot 4 / dot 5?
or

please just lead this fish to the proper water. thanks

One of the few maintenance anythings I take to our local Toyota dealer. With the SST they have it gets all the brake fluid flushed from the ABS circuit, etc. Just not worth my trouble.

i too am about to flush my system. had the same questions you have but in the end realized that flushing with generic dot 3 and doing it regularly, every couple years, is better than not doing it at all or relying on the dealer who still might not do it right.

I'll be using AutoZone dot 3 i got on sale. not sure synthetic or dot 4 or dot5 is worth it and it makes sure that anywhere i am , any gas station or travel center will have brake fluid if i need to add for some reason.

@spressomon - ^ If you can trust them to actually bleed all 4 corners, not strip the bleeders and replace the bleeder caps....

Dont use DOT 5 ( its silicone type) 5.1 is backwards compatible - if you must.

DOT 3 in basic terms will last longer than 4 or 5.1- its less hydroscopic.

I use Toyota DOT 3 if its easy to find otherwise Valvoline synthetic Dot3/4, Prestone Dot 3 is fine too (imo). The change interval is more important than brand selection- 24-36mo +\-. Buy a brake fluid tester and check moisture content regularly (at oil change intervals- )

 

[jerryb]

yup, wouldn't trust them at all. haha.

dot 3 is cheap, I've not had an easier car long term, to deal with brake fluid changes than this one.
You can just let the pump do all the work pushing old fluid out through the rear. Then deal with the front whoever you like.
Half the job gets done by the accumulator.

Looks like I'll be going to the dealer. Where are you guys finding dirt roads to activate your ABS? LOL, I must live too close to the city. This was a ridiculously easy task for my LS430, as I didn't need to do all of the ABS activation.

 

[KFunk740]

I don't know if I'd even worry about that step. My brakes felt rock solid after first bleeding. I have gravel and dirt roads right near my house, but couldn't really get ABS to activate at all. The thing just stopped as it should, no spongy feel. I've only ever had it kick on in ice before. After failing at ABS activation a few times, I just re-bled again, and called it done with no further issues. I think the system must self-bleed some, not sure.

My fluid appeared the same color as wyattroa's was here. After reading these threads about the $4k ABS actuator tool, I decided have the dealer add it to my timing belt/water pump job.

When I picked the vehicle up the fluid appearance was the same as before. Unhappy, I took it back in and they swore up and down they flushed it. I then took it home and flushed it myself. It ran clear golden immediately on the fronts and almost immediately on the rears. Turkey baster of fluid from the reservoir was also clear golden before I began the flush. So the moral of the story is that the reservoir can distort the appearance and the paper towel method isn't foolproof. But the job is so easy I wouldn't pay the dealer to do it again. The bleeder screws are accessible without removing the wheels or jacking up the vehicle.

One thing to add is that the brake booster does almost all of the work, but the key needs to be in the ON position for this to happen. FSM states to turn the key ON, wait for the accumulator to finish running (30-40 sec), then pump pedal 20 times, then continue with flush procedure. Two 32 ounces bottles was perfect with a little to spare.

Anybody has the current part # for the brake fluid for LX470?

Picked up the Toyota DOT 3 Brake Fluid from the local Toyota dealer. Used the 15% off Costco coupon (actually just mentioned the Costco 15% off coupon), and got $7 per bottle including all tax/fee.

Did mine last week when I replaced my rear differential seal. I used dot4.

The bleeding process certainly helped out by removing air pockets/bubbles on the line making the pedal more responsive. Huge difference.

 

[AFei]

Did mine yesterday, and had a question. So when bleed the rear brake lines, it seemed lots of fluid could come out. Should I wait until the fluid stopped or just watched for it clear?

Thanks!
