Default Front brake nipples.

Hi ,can someone tell me what front brake nipples fit my 1996 1500 pace truck. The one that was in got chewed up,and it seems to be a 3/8-16,but all the ones for sale are 3/8-24.
Has my truck had the wrong ones fitted.
Regards.

By nipples, do you mean the bleeder valves? I'd pull the bleeder from the other caliper and stuck a vacuum cap turned around into the hole to keep the fluid from leaking out. Then check the thread on a thread checker at the hardware store.

To be honest, I've seen them break off from rust but I've never seen one damaged when the caliper wasn't damaged.

Yes bleeder valves. We know what the thread is on the one taken off,its a 3/8 UNC X 16 ,but can,t find any of those to buy All the bleeders for sale seem to be 3/8 UNF X 24.
Thought maybe someone had put the course thread in there,instead of the fine thread.----just dont know.
Regards

Something I've run into over the years is some suppliers go metric. Others still go SAE. The same caliper will fit other vehicles. The caliper I used on my '96 Ram 1500 was the same part and number I used on a 1993 GMC C2500. If I hadn't marked the boxes for the vehicle it went to, they were identical. 1980's and 90's were a mix of SAE and Metric parts.

How did the bleeder get damaged anyway? I can't think of a way that wouldn't require the caliper to be replaced.

I think you need a Dorman 105407. They're M10x1.5

25.4/1.5 = ~16.9 TPI and M10 is pretty close to 3/8"

I could be wrong, this was all keyboard sleuthing thru numerous websites and cross referencing part #'s until I finally found one that ACTUALLY listed the thread pitch.

Let me know if I'm right or wrong!!

Think I would just give in, and replace the calipers... not like they are really expensive, and you are going to have to bleed the brakes anyway.

The bleeder was damaged just getting it off. Owned it for 16 years and never bled the brakes,so pretty tight. Tried plus gas and heat,came off eventually,could use it again but its looking a bit chewed up.
Regards.

Generally, if the bleeder doesn't want to come out, it's time for a new caliper or wheel cylinder. At least a rebuild as the rust inside is what locks them in place.
