OEM brake pad bedding procedure

[kungfujedis]

Anyone know what the official pad bedding procedure is for the OEM pads? I'm familiar with all sorts of bedding procedures as described by pad manufacturers (and by people in various threads i searched), but I would like to know what the 'official' OEM procedure is. Best I could find in the workshop manual says:

"Carry out test braking while driving at low speed because the effectiveness of the brakes may be reduced during the
initial braking operations.
Exaggerated emergency and continuous braking operations for faster bedding-in are not permitted."

Which to me sounds like 'dont do a bedding-in procedure'.

I guess this will remain a mystery

Just drive moderately for a few hundred miles.

No special process required

From the owners' manual:

Brake discs and brake pads only reach their full effectiveness after approx. 300 miles/500 km. Drive moderately during this break-in period

I always assumed that was for new owners since it refers to the break-in period of the car in general, and they had already done some kind of bedding procedure. But maybe they do nothing off the production line.

The workshop manual may, MAY be saying for the techs to not do a bedding in for some sort of legal reason pertaining to how you would be driving to do the process. Not necessarily saying a bedding in process shouldn’t be performed. That being said I do not know if it really shouldn’t be done, but that sounds odd to me for a basic road car. I’d probably do one however it’s not technically needed.

The bedding process is aggressive so all that is legal speak to make sure people aren't crashing shit while doing it.

A brake pad is a brake pad. Bed them in like any brake pad.

I'm sure you are right. I typically follow the pad manufacturer's procedure; and I have seen some significantly different ones, which is why I was wondering where the OEM pad falls on the spectrum. My DBA street pads for my WRX say 10 stops from 30 mph; and then no hard braking for 100 miles. While my DTC-60s for the Supra instruct a series of faster speeds ending in 'race' speed with hard stops. Seems like the OEM supra pad is probably more similar to the DBA pad instructions. Ive been swapping back and forth between OEM and DTC and my bedding procedure has worked out fine, I was just curious if there was a spelled out procedure.

Yea more aggressive pads on average, need more aggressive bedding in.

I bought my Supra from a dealer this summer who had had the vehicle transferred from another dealer (40 miles apart). Hence the ODO was not at 10 when purchased, but 45. I noticed rust on the rotors but expected it to clean up. I am now at 1000 mi, and the photo shows what the front rotors look like dry (top two) and just after car wash (lower ones). The pattern that you see was there basically from the moment I had purchased it. What do people think this is and should the rotors/pads be replaced? I do not have brake shudder or vibration but am not particularly impressed by the brake performance. The rear brakes look nearly brand new and show light & very even rust after wash, added a picture of them as well.

 

[kungfujedis]

Doesn't look concerning to me. Rust after washing rotors is totally normal. I think I had a similar ring pattern when my car was new. I believe it evened out after I started going to the track and actually braking hard. You aren't braking hard enough

What aspect of brake performance is lacking? Soft pedal? Not enough bite? Not stopping hard enough when threshold braking?

 

[razorlab]

Press the brakes harder and that rust should more evenly go away.

Rotors have high iron content so they rust fast when wet.

 

[deldiablo]

Thanks for the replies. Brake performance: I feel the pedal to be relatively soft , brakes not biting hard. This is my first new car, and I've only driven new rentals before on which little pedal effort led to pretty strong braking. I have to step on this car pretty hard to slow down quickly. What is odd is that the dark black zones on the front rotors do not rust, it is like they have a significant layer of brake material deposited on them? Left front looks worse than right front. Rears feel perfectly flat, while fronts are grooved, mostly towards outer edge. I've seen one other Supra nearby, and it only has fine circular lines on the fronts, rotors look much more like brand spanking new.

Hmm. Your Supra should outperform rentals. Or at least match. And it's new? Odd.

If you get free oil changes and such I'd mention it the next time you're there. Dealers don't like warranty work as much as other work, but I think they'd still take a brake bleeding job if they agree with you on the pedal feel.

 

[razorlab]

Again, use your brakes harder. Yes, harder than you currently are. Doing a couple threshold braking events from 80mph should clean it right up. Not cleaned up? Brake harder.
