They make drop spindles for an S10 that would bolt on.

Anyone have a part # for a postal mail carrier S10 master cylinder? Would be most helpful...

@@jlee3568 so... I have found that the S10 master with a 1" bore is not quite cutting it. The peddle travel is ridiculous. I'm going to a 1.125" bore from a mid '90s 1/2 ton next to tighten it up. With stock brakes it probably is fine. The booster must be stronger or something, factory 4th gen F body is a 1" bore (my front brakes are 2001 Trans Am) so it should have been fine. Just look up a master for a 2001 S10 on RockAuto, just keep scrolling and you'll find the RHD mail carrier version.

thanks for watching. I just kept the stock Malibu combo valve. works great! Please give the video one of those up thumbs if you don't mind.

The 4x4 blazer axles are too wide to use without making major changes to the wheels and tire setup. It's good to know there is some other options!

It's basically the same. if you use the older S10 truck spindles with the smaller brakes, you can get aftermarket drop spindles.

Auto zone I believe

Search for a PV-101. It's a disk/disk prop valve and connects up just like the original.

S10's came with 15's. I like the 17" look better though.

@@BurnoutsAndRotorblades thanks I appreciate it a lot, keep on burning rubber! ✌

Technically no. The proportioning will be a bit off but thats it. The need for the new master comes from changing over the rears from drum to disc.

I did when I changed the rear from drum to disc.

I did just hand-bend the lines around to the other side. My lines were in good shape, so if yours are rusty it might not work out well. If you do the discs in the rear you’ll need the s10 master cylinder.

Before I wondered if I could stop in time, now I have to be careful to not lock up the brakes.

Thank you so much

@@BurnoutsAndRotorbladessame here ! i have to be careful not to lock up . i also swapped out prop valve to a disc/disc. do you have a bit of travel on the brake pedal with the blazer master ? had a 79 TA disc/disc Master with 1 1/8 bore & switching to the s10 blazer 1” bore master made a longer pedal difference

That is a great question, but. . . I mostly use this car for full-sending used tires to their final resting place. So, it's not a precision driving instrument. Secondly, the car is so willowy and the front end has every stock piece of rubber from the 1980's still in it. There could be some hidden bump steer, but I honestly haven't noticed if there is.

I believe so.

yes you can still use 15 inch rims

You have to go bigger I believe if the rotor is 14” you need 18 or better

@@dat_mf_tae9865 rotor is still 10", it's a little thicker than g body. The right 14" wheel will fit.

I would not recommend that. Drums require more fluid to move than discs.

Any of the blazers of that bodystyle will work. I believe Bravada parts will work, but I can't confirm. Just check the codes in the glovebox.

@@BurnoutsAndRotorblades Thanks for the feedback I can verify that Oldsmobile Bravada years 1998 thru 2002 will fit on the G bodies as well

I really only know about the way I did it. I spent a ton of time researching what would work with what I have and the way I did it was the only option I found. This would be a great question to pose to a forum where experts can weigh in.

If you are looking for which brakes bolt up to the stock axle, I don't know. I only did the rear disc brake upgrade on the Ford Foxbody Mustang axle. That can be seen in this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_Jqql4zOLlE.html . For disc brake options for the Stock Body rear axle, go to www.gbodyforum.com and search for rear disc brake upgrade. That's all the help I can provide because I have no experience upgrading the stock Gbody rear axle.

​This may be what I'm looking for I swapped a 1998 mustang GT into a 1982 Buick Regal trying to figure out if I should buy a new master cylinder or use the Ford proportioning valve or both. This car runs 12 flat in a quarter mile I can't be racing when my brake pedal goes to the floor.​@@BurnoutsAndRotorblades

Mark gochnour you can use the older style spindles, but then you’re stuck with old style bearings, discs, and calipers. I don’t know if there is a 2000 blazer drop spindle.

I just used the stock combo valve with no issues

Did you have to change the rear brake lines as well?

I didn't look up stuff by part number. Maybe a dealership can give you a parts breakdown with parts numbers to order from.

@@BurnoutsAndRotorblades I meant like...what am I asking/looking for (by name)? Upper and lower A-arm? Spindle?

Negative. It works great with the stock stuff.

So are you using the stock old proportioning valve that came with the car

I did for a while.

did you make sure the combination valve is properly bled?

@@BurnoutsAndRotorblades ok thanks for the reply bro. I'll drag my tools along lol.

if I’m 100% honest, it’s been too long and I don’t remember. Sorry, but you have to carry metric and standard.

the wheel lug pattern is 5x4.75"

Negative. Did you get the part number I specified in the video? (AC Delco 174-750 or Duralast NM3068) If you didn't that might be the problem. Either the master cylinder might be the wrong one or the lines on your car might not be the same metric line nuts that are on my car.

@@BurnoutsAndRotorblades I took it of a donor 2003 blazer at the u pull it yard

There are multiple choices. One has a tall reservoir that won't fit under the hood. It is possible that the one you pulled is the wrong one. I had to go back to the parts store several times before I found the right one. The really annoying part about it is there are no definitive markings to identify the part number.

@@BurnoutsAndRotorblades thanks

North Las Vegas Pic a part

I did both, but. . . my rearend is not a stock gbody rearend. It's a foxbody mustang rearend.

@@BurnoutsAndRotorblades thanks for the reply !

No, must be 2wd Blazer. I had to get my spindles out of the States as there were none in any wrecking yards in BC or AB.

I'm just going to be honest and say I don't know. The front 2wd vs 4wd spindles look different in a quick google search, but I can't say for sure without them in hand. The belltech stuff I have no experience with. I would call belltech and ask to be completely honest. I'm sorry I cant be more help. Good luck.

If I'm honest, I don't know. You can compare the bore and stroke to the recommended master from the aftermarket source. Best bet is to call the aftermarket company and ask.

I used some from an S10 because mine were old and crusty.

Anything with a bolt on caliper will fit. You just need the right adapter bar or make your own. I made one to fit 2002 Trans Am because I wanted no bigger than 16" wheels. Rotor is 12"×.875 IIRC.

I did not.

Yes, but the brakes are smaller.

yes it does!

@@BurnoutsAndRotorblades what would happened if I don’t change the cylinder

@@richardeddings7259 if you go from drum to disc in the rear the amount of fluid that the stock master sends out will be too heavily rear brake biased and cause the rear to lock up before the front really starts working. At least in theory.

Ok do you think the 2000 blazer brake booster will work on g body

I used the stock booster with no problems.

@@BurnoutsAndRotorblades oh alright then thank you so much for your quick answer. If I may ask 1 more question. Is the rear the same thing where I can use the Blazer stuff to bolt up like factory? I know that I would probably need to upgrade the rear lines.

@@BurnoutsAndRotorblades got ya. Thank you so much for your help.

The honest answer is, I don't know. However, if I do a super lazy search for GBody spindles on summit racing the '78 El Camino is grouped in with the other Gbodies. I have never tried to put anything smaller than 17' wheels on the front of mine post brake swap so I don't know for sure, but the 2000 Blazer did come stock with 15x7 wheels. Wheels were gone when I got the brakes. www.summitracing.com/parts/sum-csum77m500/applications/make/chevrolet/model/el-camino www.google.com/search?ei=QyJBXeaaIa3J0PEP65GqgAs&q=2000+blazer+wheel+size&oq=2000+blazer+wheel+size&gs_l=psy-ab.3..0i70i251j0i22i30l3.2416.5070..5239...0.0..0.293.1183.0j4j2......0....1..gws-wiz.......0i71j0j0i10.0I_xTSrS-7E&ved=0ahUKEwimyMzosd7jAhWtJDQIHeuICrAQ4dUDCAo&uact=5 I didn't use a blazer rear. I have a whole other video about using the Ford 8.8 rear and then using the Blazer rear discs on that. To be honest, I don't see why you couldn't make the Blazer rear brakes work on the stock 7.5, but it won't be bolt-up. there will at least be drilling of new holes.

is there a copper gasket on both sides of the banjo?

Yes on both sides

the banjo might be uneven. try milling it smooth.

I believe so.

I think the S10 pickup has a single front caliper and makes it a moot point. Here is the link: gbodyforum.com/threads/gbody-lower-control-arms-and-spindles-same-as-s10-and-blazer.65689/#post-588599

Yes all g body regal, cutlass, elco, Malibu, monte carlo, grand prix it's all the same

go to my video titled "GBody LS Brakes' E-Brake hook-up | Caprice springs | Window tint PSA | #FamilyBurnoutWagon EP25" through the playlist or just copy and paste that title into the RU-vid search bar. I explain it all in that video. Thanks for Watching and subscribing!

You can, but it won't be much of an upgrade. It is a single pot caliper. The 2000 Blazer has a two piston caliper.

yes.

WHAT ABOUT A 84 Buick Lesabre Limited g body same as caprice?

the 80’s caprice is a GM B-Body. A very different chassis I don’t know much about. The most honest answer I can give is, I don’t know. Sorry I can be more help. I found this for the rear: www.google.com/amp/s/www.hotrod.com/articles/ccrp-0805-gm-drum-brake-to-disc-brake-swap/amp/

I don't have any experience with C10's.

@@BurnoutsAndRotorblades may be my service. I've seen the brake upgrade videos from different places but I'm very interested in watching yours. Judging by the comments it's pretty detailed and informative. I'll keep trying and thanks for putting this content out
