Okay, I know I could look it up. However, due to time constrants I am hoping someone knows off the top of their head what the venting clearance is supposed to be for the rear brakes. I need to reset mine as I just found that the ebrake was partially ingauged when I set it last.

Thanks

I can't confirm it off the top of my head, but I think it's supposed to be set at 32 thousandths, or .032 on your feeler gauge.

My feeble brain tells me .006". I think that .032 will give you a long pedal.

6mm between piston and disk (no pad) If you adjust with pads in, take out the retraining spring.

Ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding, ding... we have a winner:

.004

Factory manual stated .008 and all of the Haynes/Clymers were drafted off that figure.

Then the factory sent out a TSB stating that .004 is correct. Adjust on the high side of your runout obviously.

Wow! You might want to check with a therapist but I'm pretty sure taking 9 years to express your feelings is not healthy. (IMG:style_emoticons/default/poke.gif)

Nothing like dragging up an old thread to remind myself how valuable Eric's tutorials have been over the years.

Resurrecting an old thread.

If the 'correct' venting clearance is 0.004"is there any downside to a lesser clearance, such as adjusting each adjuster so the the relevant pad simply just 'kisses' the rotor, then backing it off very very very marginally to give minute clearance? (with hand brake cable disconnected of course).

In other words, applying the spirit of the adjustment specification, if not the letter of the adjustment specification?

Why do I ask? Well using with feeler gauges in that area is pretty fiddly and I'm not sure if in practice it is necessary. I understand the reasons for not having too big a clearance. Just touching then a tad loosened would seem to my mind to do the job.

Yes? No?

Thanks

Dave,
.004 clearance is pretty minute. Literally, that's the same as the width of a piece of human hair. It would be hard to get that minute a measurement going off feel. Chances are you would have way too much clearance.
