Tekniq Posted June 28, 2005 Share Posted June 28, 2005 Hey all, I don't really have the money to address it right now, but on my '98 GS3, my brake pedal seems to travel awfully deep when foot pressure is applied.. almost to the floor. I don't know if it's normal on these cars as mine is the first I've owned, and bought resale last year. But this has always sort've interested me.. Lexus techs have been through the car on 4 occasions for multiple checks and what not, and they've never mentioned a problem with it. Is it a worry with no reason? A problem with a fix? Or an adjustment that can be made somehow, even by me? Thanks in advance, TEK Quote Link to comment Share on other sites More sharing options...
Win Lowe Posted June 28, 2005 Share Posted June 28, 2005 I would have it checked again could be the brakes needs bleeding, is the fluid level low? could be a master cylinder prolem too. Good luck. Win Quote Link to comment Share on other sites More sharing options...
TurboGS300 Posted June 28, 2005 Share Posted June 28, 2005 Alot of vehicles have a threaded rod going into the master cylinder that allows adjustment of the pedal height. Not sure if the 98GS3 is that way. <_< Quote Link to comment Share on other sites More sharing options...
monarch Posted June 28, 2005 Share Posted June 28, 2005 If the brake pedal sinks to within an inch or so of the floor then whomever last worked on the brakes might have gotten some air bubbles in the brake fluid. The solution is to bleed the brake fluid as described in the factory manual. The factory manual also give the spec for the proper brake pedal height. This all assumes you have factory pads and rotors. If they are aftermarket, then the factory manual can't necessarily be used to diagnoise aftermarket brake wierdness. Toyota brake master cylinders last at least 20 years so the chances of one being bad are extremely remote. Quote Link to comment Share on other sites More sharing options...

Win Lowe Posted June 29, 2005 Share Posted June 29, 2005 “Toyota brake master cylinders last at least 20 years so the chances of one being bad are extremely remote.” As with most things there is always an exception, I had a master cylinder go out on a 87 Toyota Cressida after 5 years.
