Bosch Pads and Rotors Review- 100 series/LX470 (1 Viewer)

[CruiserDog]

* THE DECISION PROCESS AND INSTALL REVIEW

-I bought my 2006 Lx470 with 140,000 miles and the brakes felt like they have been on there for as long as it has been driving. The brake pads where almost down to the metal and the rotors were as wavy as the mint 400 race course.

-I was faced with few options in replacement brake pads and rotors. There where even fewer good options in my opinion. I narrowed it down to Slee brake setup that most people like and Bosch setup that seemed to be unheard of in the forum.

-Slee brake setup would cost $320 for the front rotors and $364 for the rear rotors / with most pads costing around $100 for front and back(EBC brake pads).

-Bosch Brake setup costed $104 for the front rotors and $110 for rear rotors / with Bosch pads costed $71

-So I decided to go with The Bosch setup due to it being a reputable german company in my eyes. the installation was straight forward and relatively easy compared to other cars I have done in the past.

-The old rear rotor gave me some trouble, but thanks to the great people on IH8MUD I got the info to remove it with easy.

* 10,000 MILE REVIEW

-This brake setup has seen about 10,000 miles now and has seen at least 1,500 miles of towing 6,000 pounds.

-There is great improvement in braking performance and lower heat emitted from the wheels after repetitive braking / long duty cycle.

-I have yet to feel brake fade during daily driving and towing. I have noticed a slight brake squeak after driving in heavy traffic.

-After my last oil change a 1000 miles ago. The brake pads have worn less than a quarter inch and the rotors seem to normal grooving consistent with 10,000 miles of wear. There is no warping or choppiness in the brake feel.

- I hope to continue this review the longer I have these brakes.

i'm in need of replacing the brakes all the way around. forgive my ignorance b/c i've always just had dealer service my brakes, but i think it's time to start doing them myself. what specific parts did you order from Bosch?

 

[montegofd3s]

Do you mind providing a link, company, or part numbers of what you ordered so I may do the same? It is time.

If the OP doesn't weigh in with part numbers, you can get what you need in Bosch parts online from a auto parts store like Advance Auto or through Amazon. Just go to the relevant web site, type in the year, make, and model and search for Bosch brake pads and rotors. I know that Amazon has the F/R Bosch pads and rotors in stock for the 100s for a decent price. When you do the front brakes you will also want to do the wheel bearing service and spindle bearing service. One of the vendors here on MUD, Cruiser Outfitters, sells the front wheel bearing service kits if you need those.

And another vendor, Slee Off Road, sells a slick tool for greasing the spindle bearings.

This is not a easy project for a first time wrenching project. Took me many hours to remove and replace the brakes and I consider myself as a decent mechanic.

Are the bosch brakes still wearing well? I ordered some for the fronts.

 

[montegofd3s]

I just popped these on this weekend (front and rear). Seem to bite nice, great price, and high quality. This is a good kit. Thanks @CruiserDog

They seem to wear pretty well. I use them pretty hard. I'm guessing I will get 40,000 miles out of them probably less

 

[Scoin]

Did you use the OEM shims with these?

Out of curiosity, why did you not go with OEM rotors? I've used them on 80s and 100s with good results and they cost about the same as these.

Pads vary and seem like a personal choice, I generally use Hawks or OEMs on all my vehicles.

Also, you state there is lower heat emitted, how did you measure this? Do you have pre/post temp data using a temperature gun? This seems like a lot of testing and environmental conditions would come into play before and after hardware was changed. Additionally it would seem to be very time consuming and expensive for an individual. I'm not trying to be jerky, but a statement like this without data to back this up is just an opinion.

Thanks for posting another alternative with good feedback.

Don't flame, but the rears are drums on the 100 series. Are these Bosch for a conversion to rear disc? I only need pads for front.

As far as I know the USA market 100 Series are all rear disc brakes. Therefore they have rear “disc” rotors.

I hope this answers your question.

Yeah, I feel like an idiot. The one time I had the truck into the dealer to take my security lug nuts off because I had no key and all other attempts to replaced failed, I had to wait a long time for them to get regular lug nuts in. While waiting they said my rear brakes needed done. I said okay and later read the parts list was a rotor/drum kit. My eyes went to drum and assumed since what I see when I look in there on a glance is a drum looking housing. Now I see the caliper and rotor.

I liked the Bosch when I ran them but man they kicked out dust like no other pad on my 100. OEM is what I went back to and they seem to work great... with only minimal brake dust.

Greetings and thanks to Cruiserdog for starting this thread.

I had a different experience w/ Bosch Quietcast front rotors. I replaced my front rotors (and all the requisite races/bearings/seals/pads) in Sept of ‘17 about 19k ago on my 2001 100(@222k now).

They now resonate/wobble enough to justify either turning or fully replacing. I think that’s been the case for maybe 3k, so mine were good for a little over 15k.

I’ll turn them first, but I’m going to guess that won’t to hold for long, assuming there’s enough thickness within specs, which I think is the case.

Maybe nearly 20k of average use is respectable for such a heavy vehicle, but I think I’ll replace w/ either the Slee favorite - Disc Brake Australia (DBA) rotors or OEM Toyota rotors.
Here’s a list of all the bits from TLC for OEM stuff.

And to the fellow who thought he had drums - likely you do in the rear. Toyota LC’s have a clever (Saab used these, too) rear rotor w/ small drum e-brake system, which is independent of the rotor brake hydraulic system. I’m sure there’s a cool thread around here somewhere about that.

If I learn anything worth sharing about the turning of these disappointing Bosch rotors, I’ll follow up. I do know that looking back at Amazon reviews, there were many complaints of rotors warping (bunch’s different vehicles) & poor customer service to dissuade me from buying them in future. I’m honestly surprised, as I’ve generally regarded Bosch as ok stuff. Of course, it could be just bad luck.

If anyone has any particular recommendations w/ OEM versus DBA front rotors, do tell.

Thanks.

Scrapped the rotors instead of turning the warped Quietcasts. Installed Toyota rotors. 20k later, they’re still good.

Appreciate you checking back in. I’ve been curious about replacing my OEM brakes with anything aftermarket since I tow cross country, and I think the answer to that is pretty clear.
