Brake Pedal travel question
Question: How far down does your brake pedal go before you feel the brakes start to grab?
I have new brakes/rotors all around. New fluid flushed through, bled with speedbleeders. Parking brake is adjusted well and holds the car on a hill. Brakes aren't spongy so I'm convinced it's not air. No calipers are hanging -- the brakes work fine, but I'm concerned about pedal travel. It just seems that my pedal goes a lonnnng way to the floor before I get any braking action. The brakes just start to grab when I pass the resting position of the accelerator pedal. The only reason I really noticed this is because my other car is an 02 Tacoma, and the brakes grab pretty high up on the pedal -- however it has drum brakes in the rear, so I would expect a different braking system to act differently. If my pedal travel is too far... how would I go about adjusting it? |
What happens if you pump the brakes? Pump them 2-3 times as you're stopping to see if you have air in the lines.
Disc brakes, as far as I know, don't have any adjustment. As the pads wear down they move closer to the rotor. Have you checked the master cylinder and vacuum brake booster? |

If you have you already done this procedure and still have the issue I don't know what to tell you to try. Edit: I did the search and found a couple of topics/posts that describes how to do the 40 pumps of the brake pedal procedure, 1 post links a PDF of the Toyota FSM/shop manual also describing how it's done. In the link below read post #83 and it has the link to the post with the PDF if needed. 5th Gen 4Runner Brakes Upgrade (for 4th Gen 4Runner) |

How have I been on this forum/in communities since we got this thing in 2003 and I've NEVER stumbled upon this info in any searching or just random reading? Going to give it a whirl. Thank you so much Edit: It didn't seem to work for me, however I am going to try again and read that PDF with a fine tooth comb. It seems a little ambiguous whether the key should be on or off. I thought it was off, but I caught something in there about leaving the key ON for the second 20 pumps. |
