Shaft Issues.... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Like the title implies,

The shaft on my 3" drop spindles is too short. my brakes are fairly new so I'm considering pressing out the spindle shaft on the drop spindle and pressing in the the shaft from my stock spindles.

has any one ever done this or had it done? A friend of mine has a 20,000lb shop press I'm thinking of going over to see what i can accomplish. any input will be helpful.

Correct, i got the spindles for the 1" brake rotor. but since i bought the spindles at the swap meet, exchanging them for the spindles that take my 1.25" rotors is not an option.

Hopefully some one can stop me from making a mistake, or help boost my confidence in pressing out the spindle shaft with my buddy's 20k lb press.

I'd buy a pair of light duty rotors and bearings before I risked cracking a spindle.

x2 on the light duty rotor and caliper swap.

Or just sell them and buy the correct spindle for your 1.25" wide rotors.
Don't risk screwing up your truck or someone elses.

the spindle stub is swaged once it is pressed in ... i have doubts of whether you'll get it out of the spindle body casting without damage to one of the other

Ronm909, thanks for the question! some times i get too excited and have trouble making myself understood

Tx Firefighter, lolife99 & Shane, thanks for your input guys i guess it wasn't that good of an idea. I'm glad I asked.

So i decided to get the 1" brake stuff rather than try and press out and swap the spindle shafts. For some reason it was really easy to come to terms with the newly incurred expense once you guys voiced your opinions

. I got new 1" rotors & wheel bearings, will be getting reman calipers, and dust caps next Wednesday when Pepboys gets them in stock.

I plan on taking the calipers apart to have them powder coated "Torch Red" and re use the piston seals since they are brand new. Hopefully this resolves my year old front drop/brake dilemma so i can move on to the rear cnotch and missing shock absorbers dilemma

Hopefully get to drive it a bit this summer, the wife already asked "when are we going on our next day trip in the blazer?"

ok gang, what are your thoughts?

Tx Firefighter · 03-19-2010, 07:19 AM

I powdercoat a lot of calipers that same way.I get reman calipers from O Reilly, disassemble,coat and reassemble.

Thanks for the encouragement Tx Firefighter, the calipers are in!!! As soon as i paid for them i took them apart

by blowing low pressure compressed air in the brake line fitting and had the pistons out in no time. I pulled the rear calipers off the truck already now i just need to take out the piston and hopefully will drop them off for powder coat MAÑANA

Hopefully we will have reassembly pictures courtesy of the wife and her digital camara

some time next week

Well, I managed to remove all the O rings and seals from the calipers tonight but I managed to tear the outer seal of the right side caliper. I'm such a rookie

i guess i will have to go look for another seal. but hopefully I will be dropping off the calipers for powder coat tomorrow. and get that seal in the mean time.
