brake booster and cylinder upgrade

[Clone TIE Pilot]

You can upgrade to a b-body master cylinder. I did.

I think the lines have to be reversed for a B body master cylinder.

Nope, there are some that use different size fittings. I'm not aware of any reversing of lines being necessary.

Some people have said the B bodies are reversed and had to bend the lines around, perhaps it varies by year?

Could be. I used a 1990 caprice application for mine and the lines lined up. The later ones, 91 and up might be different from earlier versions. I wouldn't look to them for a replacement. I think it's the ABS that makes them different.

How do you find the braking with ab body (90 caprice) master cylinder? How's the pedal travel? Are you running stock front brakes?

Pedal travel is good, not as far since the volume being pushed is increased. Pedal effort is increased because of the larger diameter cylinders. Brakes are stock. Feels more like a B-body's brakes.

Just something else to throw out there, many newer cars, esp. FWD have a diagonally split system (LF-RR, RF-RR), meaning it would not be compatible with a front/ rear split system such as in G-Bodies. Not 100% sure if 2000-2005 monte is diagonally split, but certainly something to look into.

 

[G_Body_Enthusiast]

Distribution (front/back or diagonal split) would be determined by the plumbing at the proportioning valve, not the master cylinder. Reason being, drum brakes require a residual pressure valve and later cars having 4 wheel disc brakes don't require it. So for drum brake equipped cars, it would have to be a front rear split system 4 wheel disc brakes system are split diagonally.The master cylinder just pushes fluid into the system for the brakes to work, that's all it does. The proportioning valve directs where the fluid goes. Also, diagonally split cars have 1 bore for the front and rear lines, drum brakes master cylinders usually have a larger bore for the drum brakes. I'd stick with dual bore if you still have drum brakes, single if you have all disc brakes.

That being said, you're limited by the fittings and what they will fit.

hi has anyone ever out a 200-2005 monte brake booster and master cylinder in a 81-88 g body i own a 86 mc ss and was thinking about this swap is it possible and if so how hard would it be??
thank you

Not only is it possible, it's super easy since all the parts are a direct bolt in replacement. As we all know, all GM parts are interchangeable. What makes it even better is that pedal effort will be decreased by 30% and breaking will increase by 40%. You'll also get the added benefit of ABS. Enjoy your newly discovered upgrade. I've got a feeling it's the next big thing in the Gbody world.

Have you made this swap yourself? I didn't know all GM parts are interchangeable.
