Brake bleeding question

[NathanOfSeattle]

Getting ready to bleed my brakes on my 2000 4runner, have some quick questions:

1. Does anyone know what size tubing I should get to fit over the bleeder valves to catch the dirty brake fluid?

2. Where is the clutch bleeder valve located? I've got a manual transmission.

3. Is this the correct bleed order?
passenger rear
driver rear
passenger front
driver front
clutch

I cant answer your specific questions but I have this to say: you bleed the system with the ignition key in the run position (do not start the engine) This activates the servo motor for the master cylinder and pressurizes the system. Then pump the sh_t out of the brakes and proceed as one would with any other brake bleeding system.

I have one of those Motive Universal brake bleeder kits. So I can just do it with the engine off.

Can anyone help me with my questions?

I think the valve diameter itself is pretty standard, even if the nut size isn't. So, if you can find a mechanical drawing of a bleeder, you'll know the answer exactly.

The standard tubing that came with the MityVac fits well on both my 2K3 4Runner and the wife's 2K6 CR-V. The adapter was marked 6mm, which is a smidge under 1/4". I ended up skipping the adapter and using the tubing straight...it's either 1/4" or possibly 3/16". Since you're not drawing a vacuum at the bleeder like I do with the MityVac, either diameter should be sufficient as a drain.

Per the 2K3 shop manual, bleeding order is actually FR, FL, RL, RR. The 2K6 manual doesn't really seem to have an order beyond saying front axle first then rear...no specifics on left right so the front-rear order is probably because something had to be first in the procedure. Obviously, the 2K could be different. Seems like the CR-V also had a bleed order that violated the "farthest from master cylinder first" rule of thumb.

Hmm thanks. Do you know where the clutch valve would fit into that sequence? And where exactly it is located?

A stretchy silicone rubber tube with an 1/8" (i.d.) can do you. Probably a 3/16" tube would work but the smaller tubing is better to prevent self-draining and bubbles rising up.

A 10mm flare nut wrench should fit the nut, although I have a rebuilt Toyota front caliper with an 8mm nut.

No clue. 2K3 was the first year of the 4th Gen, which doesn't have a manual transmission. I admit to only being a lay person in car repair, but I don't see where a clutch (transmission part) would have any direct relation to the brake system.

Not having ever heard of "bleeding a clutch", despite owning a number of manual cars in the past, I did a Google for "clutch bleed 4Runner":

Ok thanks. Perhaps the clutch is not part of the brake hydraulic system. Previously I owned a manual 1999 BMW. As part of the brake bleeding procedure, you had to bleed the clutch valve since it was part of the brake hydraulic system.
