Russell Brakes for the Honda Prelude: Which Parts Fit

By Core Brake Parts Tech Team — Circleville, OH warehouse

Russell makes one bolt-on brake hose kit for the Honda Prelude that we carry: part 684450, a four-line stainless steel braided set for the 1992-1996 Prelude with front and rear disc brakes. It replaces all four factory rubber flex hoses, and Russell states the kit meets the U.S. DOT FMVSS-571.106 brake hose requirements, so it is street legal. Owners of the 1997-2001 Prelude are covered on the friction side instead, with Hawk front pad sets built for that generation.

What Russell Makes for the Prelude

Russell Performance lists kit 684450 as "1992-96 Honda Prelude (Front Disc, Rear Disc) 4 Lines." That describes the whole hose system on the fourth-generation car: one flexible hose at each front caliper and one at each rear caliper. Those four hoses are the only rubber in the hydraulic circuit. Everything between the master cylinder and the hose brackets is rigid steel tubing, and that does not need to change.

According to Russell, its Street Legal kits use stainless steel braided hose with zinc-plated fittings and come factory assembled, so the ends are already crimped and you are not building lines on the bench. Russell also notes that its brake hose kits are for stock applications unless noted otherwise. That matters on a Prelude: if the car has a big brake kit or a caliper swap from another Honda, confirm the hose ends and lengths still suit the new calipers before you order.

If you own a 1997-2001 Prelude, we do not currently list a Russell hose kit for your car, so do not buy the 684450 kit expecting it to fit. It is catalogued only for the 1992-1996 car.

Why Braided Lines Change Pedal Feel

A rubber brake hose swells slightly every time you press the pedal. Some of the fluid the master cylinder pushes goes into ballooning the hose instead of squeezing the pads, and you feel that as travel and softness. As rubber hoses age they can also go brittle on the outside and weaker inside, which adds to the spongy feel. Russell's own description of the kit is that replacing the OE rubber hose with its Street Legal hose reduces brake hose expansion for more consistent braking.

The federal standard that governs this is FMVSS No. 106. Its stated purpose is to reduce deaths and injuries from brake system failure caused by hose or hose assembly rupture. It sets maximum expansion limits at several test pressures plus burst requirements, and it requires hydraulic brake hose to be labeled either "HR" for regular expansion or "HL" for low expansion. A braided hose that meets the standard has passed the same rupture, expansion and fitting tests as the factory part, which is the difference between a street legal kit and a race-only line.

What braided lines will not do is fix air in the system, a failing master cylinder, or worn pads. If the pedal is soft because of air or a leak, new hoses alone will not cure it.

Symptoms That Point to Tired Hoses

On a Prelude that is now decades old, the original rubber hoses have usually outlived their best years. Look for these signs:

• Soft or long pedal that stays soft after a proper bleed.
• Cracking, bulging or chafing on the outer cover of a hose, especially near the crimped ends and where the hose flexes with steering and suspension travel.
• Wet spots or fluid residue around a hose end or at the caliper banjo bolt.
• A caliper that drags or a wheel that runs hot after a drive. A collapsed inner hose lining can act like a one-way valve and hold pressure on the caliper.
• Brake fluid level dropping. Honda's owner's manual for this generation says the level should sit between the MIN and MAX marks on the reservoir, and a level at or below MIN may point to a brake system problem that needs to be checked.

Any visible leak or bulge means the hose gets replaced before the car is driven again. A soft pedal with no leak is where you bleed first, then look at hoses.

Installing the Russell Kit and What to Replace at the Same Time

This is a moderate driveway job for someone who has bled brakes before. Each hose unbolts from the caliper at one end and from a body or strut bracket at the other, with a retaining clip and a flare nut connection to the hard line. Use a proper flare nut wrench on the hard line fitting. An open-end wrench rounds those old fittings quickly, and a rounded hard line turns a simple job into a line fabrication job.

Plan the job so you do the following in one visit:

• New sealing washers at every banjo connection. Crush washers are single use.
• Fresh brake fluid and a full bleed. Opening all four hoses lets air into every corner, so bleed the entire system, not just one wheel. Honda specifies Genuine Honda Brake Fluid or an equivalent from a sealed container marked DOT3 or DOT4 only, and warns that DOT5 fluid is not compatible with the braking system.
• Inspect the calipers. With the hoses off, check slide pins and piston boots. A torn boot or a seized slide is cheap to fix now. See our replacement brake calipers if one is too far gone.
• Pads and rotors if they are near the end. The bleed and the wheels-off time are already done, so it is a good moment to refresh friction parts from our brake pads and brake rotors collections.

Tighten banjo bolts and flare nuts to the values in the factory service manual, route each hose so it does not twist or rub at full steering lock and full suspension droop, and check for leaks with the engine running and firm pedal pressure before the first drive.

Hawk Pads for the 1997-2001 Prelude

For the fifth-generation Prelude, the parts we list are three Hawk front pad sets, all in Hawk's HB143 shape at .680 thickness. Hawk's parts lookup lists that shape for the front of the 1997-2001 Prelude Base 2.2 and Type SH 2.2. Hawk's catalog also shows the same pad for several 1993-1996 Prelude trims, including the VTEC 2.2 and Si 2.3, but our listings are titled for 1997-2001, so earlier owners should confirm the part number against their car before ordering.

• HPS (HB143F.680): Hawk describes it as a street pad that is excellent for spirited driving, with a smooth braking feel, consistent release, and gentle on rotors for extended pad life. This is the pick for a daily driver.
• HP Plus (HB143N.680): a crossover street and race compound Hawk lists for a low to mid temperature range, fade resistant, with smooth, predictable torque, and ideal for autocross.
• Blue 9012 (HB143E.680): a motorsports pad with intermediate initial bite and increased mid-range friction. It is built for track work, not the commute.

Hawk notes that all of its compounds are designed for iron rotors and are not compatible with carbon ceramic rotors, which is not a concern on a Prelude. Bed in any new pad following the manufacturer's procedure so the pad transfers an even layer onto the rotor.

Frequently Asked Questions

Does the Russell 684450 kit fit my 1999 Prelude?

No. Russell catalogs 684450 for the 1992-1996 Prelude with front and rear disc brakes. It is not listed for the 1997-2001 car, and hose lengths and bracket locations are generation specific.

Are Russell braided brake lines street legal?

Russell states its Street Legal brake hose kits meet the guidelines of the U.S. DOT FMVSS-571.106 requirements, the federal standard that sets rupture, expansion and labeling rules for brake hose.

How many lines come in the kit?

Four: one for each front caliper and one for each rear caliper, which replaces every flexible hose on the car.

What brake fluid should I use after installing braided lines?

Honda calls for Genuine Honda Brake Fluid or an equivalent from a sealed container marked DOT3 or DOT4, and says DOT5 is not compatible. Use fresh fluid from a sealed bottle and bleed all four corners.

Will braided lines fix a spongy pedal on their own?

Only if the sponginess comes from expanding or aged rubber hoses. Air in the system, a leak, or a worn master cylinder will still cause a soft pedal, so bleed and inspect the rest of the system too. Our master cylinders and brake lines collections cover those parts.

Which Hawk pad is best for a daily-driven Prelude?

The HPS. Hawk positions it as a smooth, rotor-friendly street pad. HP Plus suits a car that also sees autocross, and Blue 9012 is a motorsports compound.
