I inspected my brake pads and rear brake lining yesterday. As a DIYer, I prefer to do these things myself rather than pay good money at the casa. I noticed what I thought was a large amount of brake dust in the rear brakes. I find this unusual for a car with 25,000 kilometers. My Hilux has almost 250,000 kilometers, and the brake lining at the back is almost as think as the Innova's without having been replaced, and the brake dust is minimal.
Any help will be appreciated.
Re: Brake dust in Innova
Its either the Innova brake linings are small (surface area) and softer material than the ones installed in the hilux or the Hilux has been driven without load most of its 250K life. The Hilux has a rear brake pressure limiter valve and adjusts the pressure going to the rear brakes. If the hilux has been driven light (meaning no load on the bed), rear brake pressure has been light hence not much wear. Does the innova have a brake limiter valve?
I hope this helps...

Re: Brake dust in Innova
I was at my Toyota dealer yesterday and asked the same question. They said that the material used now is a carbon composite which is softer than the old asbestos. Safer, but more prone to wear.
The hilux most of the time has no load. But occasionally, it carries quite a big load, like building materials, a boat and boat accessories, etc. The Innova also has a load sensing valve for the rear brakes.
Re: Brake dust in Innova
We have the same problem with our xtrail. at 40k kms, the casa advised to replace front brake pads. I noticed that it produces a lot of brake dust than before and its a PITA to clean every time.
Re: Brake dust in Innova
What could be the reason why the brake pads seem so much softer now? For safety reasons because asbestos dust is carcinogenic?
Re: Brake dust in Innova
could be that the softer compound is rotor friendly?
Re: Brake dust in Innova
i think the brake bible has some tips regarding which brake pad compounds produce more dust, etc., etc. hth.
Safety first - always wear face/eye/ear/hand protection as a minimum.
Re: Brake dust in Innova
this is yet to be verified by myself. an innova user in tsikot had his brake shoe's changed and noticed that the oem (orig), is smaller than the aftermarket (bendix ct).
this could be the reason given that stopping power of innova is not good. consequently, larger surface area means more friction surface, better stopping power.

Life is getting harder and we need to make more bread...Aside from the main reasons (i think), softer brake material means quicker turn-around time for these dealerships.
But to add up on the issue, the front brakes should always wear out first (about 3-5x replacement) before the rear will wear down to service limits due mainly to inertia as we all know.

on my Crosswind brakepads, i was at the Isuzu casa the other day and wanted to purchase brandnew front brakepads, the price was a whooping p5,500. I ended up going to Walco in Banawe and got the Bendix for only P750...and yes i notice everytime i wash my car there's plenty of black dust coming from the rim.

Funny, but I never noticed the front to wear 3 to 5 times faster than the rear pads, due to inertia? often they do wear lightly more than the rear but not by 3 times, maybe 1.5 times to 2 (but that depends if you are using the same pads for the front and rear, if you are using different types, disparity can be as much a 9 to 15 times maybe more :rolleyes:). Softer brake pad materials often relate to less wear on the brake disc since it is much cheaper to replace or machine.

Re: Brake dust in Innova
I have read the thread in tsikot.com forums, despite the softer pads, the brake drum showed uneven wear thus the owner had his refaced before replacing with the wider Bendix pads.
Dumb mistakes will always be dumb mistakes, unless . . . . you learn from it, and then it will be learning experience.

soft pads na wear out pa rin ang drum? this often relates to poor material choice. Toyota had problems with the brake discs late 80's due to the locally produces brake discs (made by (TAP) Toyota Auto Parts in Sta. Rosa) due to material construction, the metal used wasn't at par with the Japanese ones at the time. The problem was corrected though and the next problem came with the cheaper pads which presented to wear the disc faster. Ask your dealer for the recommended pads, often they will tell you options which is a good choice other than Toyota parts.

sir,
as per my case, i experienced 3 brake pad replacements. no brake shoe yet. coming soon i think as i haven't inspected them. last inspection was around 1.5 years ago.
i prefer softer materials as they are gentle on the rotors. rotors are harder to find too (aside from costs) than brake pads.
