No, not unless you open the lines for some reason.

Don't use lube on the pad brackets. The caliper slide pins need lube, but are generally fine as long as the rubber not is intact.

It might be needed.

You should open the bleeder screws before compressing the pads/cylinders back into the caliper. If you don't open the bleed screws you risk pushing dirty brake fluid back into the CAB aka ABS valve module. (Thanks Dennis!) Getting crud back in the CAB module can ruin your day.

When the bleeders are opened there is some risk of air intrusion so the fluid should be bled. If you choose not to open the bleeders, risk the CAB module, and just compress the brake pads back, then no bleeding is needed.

Check the power steering fluid, and turn the steering wheel lock to lock a few times. Double check the speed sensor.

it only shuddered when turning left. turning right was normal. I added about 1/3 quart of power steering fluid. still shuddered.
only after driving it through a bumpy parking lot, did shudder go away.

when wheels off, I didn't turn the engine, but rather just to acc iginition position to turn the steering full left to (for doing right breaks), and full right for doing left breaks.

from torque chart, is the disc brake rotor locking bolt - 7? and what is the torque value for the guide bolts?

Default Re: Replacement of front brake pads and rotor

Trying to sort everything out before I start replacing the front brakes.

In doing research, one item that should be lubed is the "caliper slider pins" (referenced in this thread, as well as elsewhere). It is not clear based on all this write-up where they are. Looking at other brake repair info online, it seems they are installed in the caliper bracket, and the "guide bolts" would screw into them.......? But I may be misunderstanding something.

Do the Bosch front brakes on the T1N have these slider pins? And if so, should they be removed, cleaned, lubed, and re-inserted.....?

Are the "guide bolts" the slider pins in this application, and in turn, they should be lubed when re-installing?

If anyone has a photo, that would be a huge help.

Thanks! (and sorry if this is a stupid question)

Yes, the guide bolts (#3) are the guide pins. I did lubricate them, but also put loctite on threads. Since you have to push them through the guides, you have to put loctite on what they thread into and lubricate them, making sure none of the lube gets on the threads. Takes a little care to keep the two from contaminating each other.

Regards,

Mark
