Chevy & GMC Vans

Just recently bought a 98 Safari and the previous owner mentioned it may need new rotors. I only feel a little bit of softness/pulsing when coming to a stop. Took a look last night to see how difficult it would be to put on new rotors myself- not that difficult. The rotors look to be in good shape so I'm trying to decide if I should get them turned or buy new ones? Anyone know how thick the rotors need to be to be turned? Trying to same money to go into other modifications to the van.
Thanks for the help and I'm psyched to find such a great resource here on the web.
Cheers-Mike

Welcome to the forum, so nice to have you.

A few years back I decided to never turn rotors again. Reason being, once turned they are thinner, therefore will heat easier and warp sooner. I'd rather use the machining money toward brand new rotors. Ironically they sell cheap rotors if you should choose, about $15 each. This is the same cost to turn them.

Swapping them is very easy too, great DIY project. I just replaced mine after 100k of not swapping or turning them. I bought the best they had, $45 each at Autozone.

Welcome!

I'm not a fan of turning. If I need new pads, I just slap them in. If your rotors are warped, and the pulsing is an indicator, then I'd replace them. As stated, it is an easy enough job.

Thanks for the quick replies. I'll just go and slap on new rotors. I'm assuming if I'm throwing on new rotors I should put new pads on as well? Or can I keep the same ones on?
I know everyone on here likes pics so I'll be sure to get some up soon. Most likely in the camping section as thats what most of the modifications on my beast are!

Welcome to the site. As for your question, it's a toss up. If you are hard on the brakes then by all means go for the new rotors and pads. If you are easy on your brakes then turning the rotors will work fine. While you are at it get the 4X4 pickup disc pads. They are 20% larger and they will fit without any mods.

I've done new pads with unturned rotors, but I'm very easy on the brakes, so they tend to stay flat and mirror smooth. If you are going to get new rotors, I'd suggest getting new pads as well so both start out brand new... my 2 cents

That got my attention! Which pickup.... 1500....S10......

20% larger....20% better

Hey, SS, somewhere on the site I posted all of the part numbers. Do a search. If you can't find them I'll post them again.

Chevrolet Astro Big Brake Upgrade

Front calipers: Cardone rebuilds. Part numbers: 184122 & 184123.
These calipers are used on about a dozen different Chevrolet trucks, years 79 - 86.

Front disc pads: Wagner. Part number: SX 153
Brake hoses and rotors will still be the stock hoses for your application.

Rear brakes: Junk yard
Backing plates and all related hardware from the mid 90's full size cars. Not all full size cars have the 11x2 brakes so take a tape measure. A couple of cars to look at would be the Chev Caprice sedan and station wagon. Police and taxi versions and Buick Roadmasters. You might even go back to the 80's and look at the big Oldsmobiles.

Rear brake shoes: Wagner. Part number: PAB 462.

Rear wheel cylinders: Wagner. Part number: 51088.
The wheel cylinders have an option of using either 7/8" or 1". It depends on how much weight you cary in your van. The part number for the 1" cylinders is: 51088. Both sides are the same.
