ABS & Brake failure: 2007 LX470 230k miles need advice

[NolaNomad]

Started up yesterday to the ABS VSC lamps on and audible alarm. Damn! No brakes total spnge to the floor then some slight pressure to the claipers.
ABS lamp + alarm On, Vsc As well etc.
-No leaks in the system that I can tell, resivior level is above Max line, fluid looks good condition
-Pedal is a sponge to the floor board
-After performing the 40 pump pedal test, no booster motor noise was herd and fulid level unchanged (fluid still sittitng avove max fill line)
-ABS realy switch in the junction box clicking on and off every few seconds(?) # 88263-24020

Because these is no pump sound on start up and the pedal sponge, I'm thinking its time for master cylinder swap.
I called my local Delaer they said its a Hyroboost Master Cylinder assembly and would be around $2700 OTD for the complete unit.
-Is the Toyota Land Cruiser LX470 98-07 OEM Genuine Brake Booster Pump Motor 47960-60010 suspect to fail first? Should I replace this moter before the entire unit?
-How big a job this is going to be with the extraction, install, brake system bleed etc.?
-Any recommended alternatives than buying unit from the dealer at this cost? Any known suppliers on a used/rebuilt-refurb unit?
-I'm in Coloradado 81621 area, I live on a mountain side with a graded gravel drive, dont want to move the LX in thos condition, towing might be a challenge do to the weird angles of the driveway.

Anyone have experiance with this task, did you do this yourself? What parts did you go with and where did you buy them from?

Any direction much appreciated!
Thanks-Rob

EDIT: I tapped on the brake booster with a wrench-the motor started to pressurize , but didnt hold pressure and the fluid level went back up past the max fill line. Does this mean that I should only replace the accumulator and motor instead of the entire Unit? This would save a good bit of cash.....

Here’s a post about part numbers for early models and what they come with.

Here is the post: Brakes ...... Overdue write-up. - https://forum.ih8mud.com/threads/brakes-overdue-write-up.1230968/

There is also several YouTube videos that show the process.
Here is a good one:

There are sales going on now at Serra Toyota for 25% off and also dealer discounts. The whole assembly is about $1043 shipped for my 2003 lx, but depending on your year, the part number may be slightly different and costs may be slightly different.

Awesome, thanks!

ill let the pros chime in. But from what I’ve been reading, seems most recommend replacing the whole unit given criticality of its function as well as other parts going bad after single pieces are changed out. Again, just from my limited reading on the issue.

ive watched on a youtube video that theres a master cylinder rebuild kit from toyota for like 75 bucks, but i cant find the video
i think it was "chowcares" video

 

[NolaNomad]

Well that does make sense. I'm not sure if I can float the $3800 or close to that for this fix, parts and labor. I was thinking going with a refurb unit and wrestling with this myself to keep the cost down or at least prepping the job before handing to the Tech. Thoughts on refurb unit?

Oh I know chowcares, I'll look it up. Do you recommend this in lieu of the full unit swap?

If you plan to keep the cruiser then get an OEM unit. I bought mine for like $1500 from a toyota dealer.. Those are not that expensive as it used to be. You can also install it by your self.. no fancy tools needed.. I did my installation (first in my life) and save a ton of money and headache knowing I got it installed 100% correct. Also install new flexible brake hose lines at the same time to calla job well done!

Highly recommend rebuilt brake master units from Andy Le. He will also provide advice on installation.

I believe he sells these rebuilt units on EBay.

He is also active on the UZJ100 Facebook group.

Good luck!

A complete new unit is around $1400 from dealers online if you shop around. It is not a difficult install. Timmy the Tool Man on YouTube did a full breakdown install video not too long ago if you need a step-by-step.

I would replace the brake booster assy w/master (the whole brake master). One and done, for next ~25 years, if properly cared for.
I would only buy a new toyota.
I would only use Toyota brake fluid.

I would not overfill reservoir with fluid.
I would not spill, fluid on brake master assy.
I would not buy, a remanufactured master.

Sound like the typical booster motor failure. Where commutator has a few dead spots. This is "mostly" (90% of time) due to increased resistance in wires to motor. If so, you'll likely find corrosion on wires/screws within the boot at bottom of ABS unit (black box on master wire housing blocks, plug in).


You can rebuild the motor. You can buy good used or new OEM motor. Or buy new booster assembly (motor, pump & accumulator).
But replacing just components of the brake master, is more labor than replacing the whole master assy (the whole deal).

If fluid has not been properly care for, from day one. I would just replace the whole master with new. Replacing just booster side of the master. Will increase the brake fluid pressure. It's very likely, within 2 years, a non replaceable seal inside master, will fail. Then you be back here again, and need the master.

First and foremost: Brakes should only be worked by those, with high level of mechanical abilities and experienced with brake systems. With the age of all 100 series today, in our aging fleet. Any issue, with brake master assembly. IMHO, best and safest course of action. Have the whole brake...

Yes you are right, I'll be going for OEM. I did find a complete MC unit from Fred Anderson on Raliegh... $1048.00...shipped. Its a good enough deal that I can go new part vs. rebuilt at around $800-900. I'm stuck outside on the gravel, dont feel real great about doing this myself, might have to call a pro!

NIce! I did find a similar price from Fred Anderson so I just ordered this and having the local shop do the install. I offered to pull out the old unit to save some hours but he saidif I pull it he wont touch it afterwards.. so I'll just leave it alone

 

[2001LC]

IMHO, you made a good choice going with new.

You may want to find out how long his rebuilt will last and then come back to let us know if you still highly recommend his unit.
