575 miles on new 80 rotors--can 100 series........

[SR.GRINGO]

I just got a 94 Cruiser and I'm having it transported to me. One question that has come up is the brakes and rotors are brand new--well once it is dropped off at the shipping company they will have about 600 miles. Can I still put on the 100 series pads or should I wait till I have to buy new rotors down the road?

 

[snowcruiser]

Put them on...you will be fine. BTW Congrats on the purchase...Cheers!

 

[NorCalDoug]

since the pads are new, why not just wait until you need to replace the pads? Or...would you keep the 80 series pads as spares/back up?

 

[landtank]

The 100 series pads are slightly larger so you need to install them now or waite til the next rotor change. Some have turned the rotors which would allow you to then install the 100 series pads but turning the rotors have lead to warping issues.

 

[OGBeno]

I'd say wait until your rotors/pads wear out and then upgrade.

You probably have about 10K-15K on the new ones, depending on how hard you drive the rig.

The brakes on the 80--if new--will be quality.

100 pads will be a really nice upgrade (just did mine about a week ago or so...a definite different in stopping power and feel).

I have no complaints with stopping on my '94 80. There is no telling how old the brakes are.

I'd leave them and run whatcha got. No sense spending money where it is not necessary. Spend it somewhere else.

 

[cruiserdan]

As long as the friction surface of the rotor is still flat you will be able to switch to the 100 series pads. The surface area occupied by the 100 series pads is about 17% greater than that of the 80 series pads. In addition, you will not be able to install the original shims as the 100 series pads are thicker than 80 series pads.

If there are no evident ridges at the inner or outer edges of the rotors you should be fine.

Do remember that the 100 series pads overhang the inner radius of the 80 series rotor and the inner edge of the pad should be relieved to prevent pad overhang as the pads wear.

Very bad advice IMO.

 

[SR.GRINGO]

Thanks for all of the replies--the 100 series pads sound promising. The front 80 series pads don't by chance work on the rear brakes as well? How long will the new Toyota rotors last? I'm pretty easy on stuff--just sold a 00 5spd 4Runner with 70k and original pads.....

 

[landtank]

You can get around 100k on the rotors, depends on driving habits. I got more but I'm driving on the highway 70% of the time. The front pads don't fit the rears so they would be discarded. I'd replace the pads now. They will last longer and give you better breaking. Depending on your driving style the 80 npads could need replacing in as little at 20k.

Dan, are you saying the excess should be grinded off periodically?

 

[MrZumma]

Very bad advice IMO.

Perhaps you could elaborate?

If someone has ANY concerns about their brakes my advice would NOT be - I have no complaints about mine so no sense for you spending money where it is not necessary.

 

[cruiserdan]

Dan, are you saying the excess should be grinded off periodically?

No, it's a one-time deal at the bench grinder, done before installation.

OK Dan, exactly what needs to be grinded off?

In my mind a semi-circle of brake pad need to be removed, but exactly how much?

Without a template someone could grind off too much and then the benefits of the 100 series pad would just be wasted.

 

[landtank]

Just drive on them for 5k and then grind off the high spot.

 

[cruiserdan]

It is a very small arc on the inner edge of the pad. Rick's approach would be one way to do it. I prefer to set the pad on the new rotor and use a pencil to scribe the arc on the edge of the pad.

Uh his brakes are new..... he hasn't driven the truck... Boy thats grounds to be concerned...

 

[landtank]

My approach is out of laziness. The pads have been on for a while and I'm tearing down the axle this weekend.

Lurker,
Have you been reading this thread or did you just jump in and slam Bailey? Sr Gringo has never driven this vehicle and he said it will come to him with new OEM rotors and pads. I agree with Bailey that this truck will be fine and he should spend the money on accumulating an inventory of spare parts.
