  1. I've been reaching out to a few ole buddy's to see if I could borrow an OBDII scanner with ABS bleed functionality, but, all their scanners are like mine. I made an offer on eBay for a unit with ABS bleed, but, we could not agree on my price! Then, a couple of days ago we had a pretty good rain. So, I went out and found a deserted road, sped up to about 45 mph and locked the brakes up....once, twice, and a third time. For the past (2) days the brakes have been working fine.....no slow pedal drop. Next, I will perform an old fashion brake bleed with someone pumping the brake pedal and me under the car opening & closing the bleeder valves.
  2. Decisions, decisions.... replace master cylinder (@ shop $500) ABS bleed (@ shop $125) Now the $500 at a local shop to replace master cylinder also included the ABS bleed. But, to have an ABS bleed done on its own was $125. And, to replace the master cylinder myself is $130. If I purchase a scanner to attempt the ABS bleed on my own, most OBDII scanners with ABS bleed run about $150. Well, I decided to attempt the master cylinder replacement, and, to DIY in my driveway. Bench bleed went well, removal went well, and, even the install was not too bad. Test drive around the block, and, yes I'm still having the (very) slow sinking pedal.....so I have to assume that the master cylinder is/was not the problem. Now, buy a scanner.....or....take it to the shop just in case the issue is not the ABS bleed !!!!!
  3. This has been my 1st/only Lexus (purchased from individual) and I've only had one experience with a Lexus dealership (oil leak). I wasn't really impressed. And, I'm pretty much hands-on and always trying to learn. I'd had an issue with the front brake hose that would not connect back to the brake line (FP). I have replaced front brake hoses/calipers/rotors/pads on this vehicle. I have been wondering if air had gotten trapped in the ABS pump. I have bled the brake system multiple times.... normal brake pedal pump (2 people) Motive pressure bleeding (twice) Vacuum pump bleeding (once) I have no ABS dash lights on and have used my CenTech OBDII scanner to check for ABS error codes. No codes found. I found there are newer scanners that now activate an ABS Bleed to push any/all air from ABS pump/valves into the brake lines. Then you follow with a normal brake bleeding.. Rather than paying a Lexus tech I'm considered/shopping for a newer OBDII scanner with the ABS Bleeding function. Autel Maxicheck Pro (wired) Autel MaxiAP AP200 'C' (wireless dongle/works with smartphone) Foxwell NT630 (wired)
  4. And, in the tradition of the "American Way" (small, medium, and large) we always choose 'medium'. However, in this case I chose 'small' (the cheapest) adapter....Motive 1101 It did work ok but I did experience some leaks. I completed a brake fluid flush/purge. All new brake fluid and a successful test drive around the block. The next day a successful test drive to the doughnut shop. But, on the 3rd drive, with my wife, to the Dairy Queen drive thru I began experiencing the sinking pedal again. I have followed up with (2) additional brake bleeds of all 4 corners;, and, still I'm experiencing the sinking pedal. I will probably attempt to replace the master cylinder now.
  5. I want to flush/purge the brake system before trying to replace the master cylinder. I have a motive power bleeder, but, don't have an adapter for the Toyota/Lexus master cylinder. Does anyone in the forum have any experience or success using either of these 3 different power bleeder adapters with the Lexus RX 350 ?

  6. I have 2007 RX 350 FWD with 213k miles. The brake pedal has begun to slowly press all the way to floor when I am stopped at traffic lights and stop signs. So, I suspect the master cylinder is leaking internally. I have checked brake hoses, calipers, fittings, underneath the power booster and master cylinder, and, not found any leaks. Does anyone have any experience replacing a brake master cylinder on the RX 350 ? I've not been able to find any videos that show the procedure, but, I did find a video for the Toyota Sienna that appears to be very close to what I'd expect.
  7. I'm not sure about the foaming, there could be air in the system. As for the color, I believe that Toyota/Lexus coolant is red/pink. There's a particular bleeding technique for the 2GR-FE engine. This video is a great overview on the procedure. And the Car Care Nut in the video is located in Chicago....He just opened his own shop. Something to definitely check on the 2GR-FE is that the oil cooler line replacement has been done. Don't use a Dorman oil cooler line for this replacement!
  8. I noticed that my passenger side view mirror (RH) seemed a little loose, and, that the power movement functions were not operating. Fuses seemed to be ok so I decided that I would remove the door (passenger) panel see if I could tighten the bolts holding the mirror onto the door and test the wires with a multimeter for the power movement functions of the mirror. One of the mounting bolts had been cross-threaded. I successfully removed 2 of the 3 mounting bolts. This meant I had to pry the mirror off the door for the final/3rd bolt, which pulled the nutinsert (M6 bolt and nutinsert) from the mirror housing. And, I found that the power mirror wasn't plugged into the "Computer Assy Outer Mirror Control". Then, I saw that the plug on the mirror did not even match the connection on the Computer Assy Outer Mirror Control. Does anyone know what connection on this mirror goes to? is it for a different year or model of Lexus? Does anyone know if I can purchase just the correct connection for the Computer Assy Outer Mirror Control module? I could cut off the connector on the mirror and re-wire it to the correct connector. My wife said that I cannot purchase a replacement mirror....she said that I have spent too much $$ on the vehicle already.
  9. I found a sway bar on Ebay, in Texas (rust-free).....[16MM. Part Number: 48812-48060], and, less than 1/2 price of a new one. After installing the sway bar and new sway bar links, I took a few test drives and continued to hear a slight humm from the rear. I wasn't sure if it was tire noise due to needing an alignment or possible rear wheel bearing. I removed the LH rear caliper & rotor and gave the hub a spin. I could hear the ever so low tone of the bad bearing. I ordered and replaced both rear wheel hubs/bearings. This ranks with one of the worst mechanical maintenance chores I can remember !! Of course, the wheel hubs were frozen/rusted into the knuckles and dust shields. After unbolting the hubs I used my Thor hammer and removed them from the knuckles, but, they were both still stuck/rusted into the dust shields. I removed all the emergency brake components (shoes, springs, pins, adjusters) and then took the hub & dust shields to the workbench. I used a bolt & nut/washers to make a press between the hub and dust shield. But, the 3/8 bolt & nut I used only lasted a few turns before stripping. Off to the hardware store, I purchased a #8 grade bolt & nut, then I used an old 1/4" drive socket as another spacer against the dust shields. I also knocked out all the lug studs, I didn't have to but it felt good! I used the #8 bolt/nut/washers/socket to press the hubs out of the dust shields. I put the bolt/nut/washers into one of the lug studs holes and would place the 1/4 socket against the dust shield and tighten the bolt/nut, then, I would loosen and rotate the rub move the nut/bolt/washers/socket to an alternate position....I generally used 3 different points (like a triangle) and pressed the hubs out of the dust shields. If you notice the 1/4" socket in the photo, it is pretty much destroyed from the pressure/stress. The #8 bolt/nut held up but certainly took a beating. Yes, the hum noise is now gone and the ride does feel much better.

  11. Yes, I'm hunting down used options. Does anyone know what the difference between a light green and an orange sway bar indicate? Looks like the stock FWD (with just a sunroof) calls for the light green sway bar which is 16MM. Part Number: 48812-48060 And, the models that have the moon roofs with multi panels of glass use the orange sway bar, which I believe is 17MM. Part Number: 48812-48070
  12. The plan.... front struts front sway bar links rear struts rear sway bar links rear sway bar bushings Completed.... front struts front sway bar links rear struts And, why not the rear sway bar links & bushings you may ask ! While under the car, removing the brackets to the rear sway bar bushings, the entire sway bar fell out.....it had broken through completely in the drivers sides bushing/bracket. and, it had been broken for awhile because both sides of the break were thoroughly RUSTED. Now, to find a rear sway bar/stabilizer bar/anti-sway bar. Used - ebay - salvage yard New -dealer -looks like no one else has new sway bars
  13. Well, the RX350 has been in the shop. Weather turned on me so I sent it to the shop. One man shop and unfortunately he experienced some down time due to illness. He was able to cut the brake line, remove the brake fitting and re-double flare the brake line. But after replacing both front brake hoses it still continued to pull right when applying brakes. The problem was the ball joints. And, the old ball joints that were on the vehicle only had 2 of 3 mounting bolts holding them on….I can’t believe I hadn’t noticed that when I was looking at and working on front brakes.
  14. I ran my VIN on THR, results were a little confusing. One result shows as Japan, but, another shows Canada. I believe it’s Canadian…aayy, it begins with “2T2” Mark WMI Manufacturer Brand Owner Country Code Country LEXUS 2T2 Toyota Motor Mfg Canada Inc (CAN) TOYOTA 2T Canada LEXUS JT1 TOYOTA (J) TOYOTA JT Japan LEXUS JT6 TOYOTA (J) TOYOTA JT Japan LEXUS JT8 TOYOTA (J) TOYOTA JT Japan LEXUS JTH TOYOTA (J) TOYOTA JT Japan LEXUS JTJ TOYOTA (J) TOYOTA JT Japan
  15. Yes, I'd watched those videos before I attempted to change the brake hose. The old brake hose really doesn't show any outward damage (211K miles). But, I wanted to attempt this simple/fast change (haha) to see if it would resolve the slight right pull I'm experiencing when braking. So, the brake fitting was awkward to pull out of the old hose after I had finished unscrewing the brake fitting. And, now the brake line will fit into the brake hose ok, but, the brake fitting appears to have been spread out by the brake line flare too far to allow it go into the brake hose fitting (the old brake hose or the new brake hose). I'm tempted to take a pair of pliers and crush/squeeze the end of the brake fitting.
