Air mix screw 86 toyota 4 runner with turbo

SOURCE: 2003 Toyota 4 runner

Hi robrtsn,
As you forgot to say what the engine is in your 4-Runner....I'll give you the rule of thumb....if you have a timing chain in your engine, you'll need to check it only if it becomes noisy....If you have a timing belt, the manufactures recommend that it's replaced every one hundred thousand kilometers.....thats about sixty five thousand miles.... I believe that the later vehicles...(those with the electronic odometer fitted) have been extended to one hundred and fifty thousand, but to be on the safe side, I'd replace at one hundred thousand, especially with the number of sub standard parts that are available on the market these days....

Hope that's a help

Best regards Johngee10

SOURCE: replace front brake pad 2003 toyota 4 runner

Diagram is unnecessry.
Pull both front wheels
Work one at a time leaving the other for reference
Find the retention spring ... its a paperclip thickness wire spring... dislodge center retention loop and undo from both ends which engage brake pad retention rods.
Pull the rods out
Pull the old pads out... laying everything on the ground
Use scrap wooden wedges to pry between the rotor and the caliper ...inside and out until the calipers are fully withdrawn. Use the new pads to measure if they are far enough back.
Note... the brake fluid will have dropped in the master cylinder over many months of wear... do not fill it. When the calipers are pushed back they will fill the reservoir again... one wheel at a time.
Be sure to identify the correct pad based on what you took out and what is on the other side (if you screwed up the layout)
Make sure to take the old antisqueek backing plate from the old pad and place it on the new pad. They don't use lubricant on these anymore.
Replace the pads... the retention rods... then the retention spring
Do the other side
Then progressively step on the brake peddle until full tension is felt
Check the master cylinder reservoir... probably needs no additional fluid.
New pads will register in existing ridges in each disc in no time at all.
You should check the discs to see if they need to be replaced during this operation...using some calipers
