Re: Master cylinder clearance

I think that some more fancy aftermarket master cylinders have ports on both sides for custom application's. I do not see a good solution with those two items utilized together.

Re: Master cylinder clearance

Porta-power or a dead blow hammer would move that header just fine.

Re: Master cylinder clearance


Yeah it’s tight on both sides. I’m thinking banjo to -3an and a heat shield

No, you cut out the offending tube and weld in a different tube.

Manual brakes will move the whole master cylinder close to firewall.

I got it figured out. A master cylinder from a 1982 has standard threads. So I’ll get banjo bolts and run -3an to the proportioning valve.

Re: Master cylinder clearance

Also look at a 1982-87 G-body (Monte Carlo, Regal, Cutlass) master cylinder. Outlets are on the drivers side and have the standard inverted flare fittings. 9/16-18 front port and 1/2-20 rear port. It is the same step bore design as the 82-92 F-body master cylinder.

Another option is a right hand drive, postal 1998-2000 S10. This is a strait bore design with a 1.0" bore with the outlets on the driver side with the same 9/16-18 and 1/2-20 outlets.

Another option is the left hand drive 1998-2000 S10 is also 1.0" strait bore, but its fittings are on the passenger side of the master cylinder (like a stock thirdgen F-body). The outlet sizes are both 1/2-20.

Re: Master cylinder clearance

Banjo or not, that's going to boil your brake fluid..

Re: Master cylinder clearance

It will be fine with wrap and shielding

dent the header tube in some for more clearance before wrapping

Lookat DEI for different heat shield materials and offerings. They made thick flexible form fitting type pieces you can place in front and around the master cyl and lines.



i


i had a few setups with alot of heat around that area just fine

Re: Master cylinder clearance

Saw this on another thread. This is a Caprice, so apparently the lines are on the other side of the master:



I think the farther away you can get the lines from the header the better. Temperature has a serious impact on hydraulic / brake fluid.

Agreed, and the picture you posted seems the best route to take, especially for a street driven car.

Re: Master cylinder clearance

I was able to get about 1/2 of clearance. And I’m going to put insulated spark plug wire sleeves on them. And see how it goes.

Just be careful. When brake fluid boils, it turns into a gas which causes hydraulic failure. Losing brakes on any vehicle is dangerous for everyone.
