Today we will change the rear brake pads, brake drums, and also adjust the handbrake to. A video tutorial will help us with this work.
The process of replacing brake pads and drums Hyundai Accent
1. In order to remove the drums, first you need to loosen the handbrake. It loosens under the plastic console. The plastic is attached with two screws. You can see the location in the picture below.
2. We loosen the handbrake with a twelve key.
3. We dismantle the wheel.
4. Take a curly screwdriver and unscrew the two screws.
5. Gently tap the brake disc and remove.
6. We dismantle the brake mechanism, remove the tension springs. I advise you to take a couple of photos before disassembly. Then you can easily put it all back together.
8. Remove the pads by pulling them to the sides.
The left block with the handbrake cable, the cable must be removed separately.
9. Let's start installing new pads.
The left block with a metal piece for the handbrake should be inside. I advise you to remember how you removed it and put it back, only with a new block.
10. We take pliers and install the handbrake cable into the left block.
11. We take the right block, install it, and fix it with a “soldier”.
12. We return to the left block, and install the mechanism as shown in the photo below.
And the side that is included in the right block.
13. We fix the left block with a “soldier”.
16. We make adjustment of the handbrake.
We tighten the handbrake and try to rotate the wheel. The cable must be tensioned so that the wheel rotates easily, but at the same time, when you tighten the handbrake, so that the car is stationary.
17. We twist the plastic on the handbrake and the job is finished. Any questions write in the comments.
Be sure to change the pads on the same axle.
The handbrake must be adjusted only after replacing the pads on both wheels.
Check the condition of the rubber bands on the brake pistons.
What rear pads to put on a Hyundai Accent?
Number of original pads: 58305-25A00.
Number of original brake drums: 58411-25010.
Brake pads for Hyundai Accent 2 Tagaz practically do not have any differences in installation on different modifications this car. Unless only the dimensions of the rear drum blocks, which differed depending on the year of manufacture of the car, can be of two types for a large or small diameter. The manufacturer of the brake system is AKEBONO. Front mounted disc brake pads rear axle- drum (disk not provided).
Front brake pads for Accent Tagaz
Front pads for Accent 2 Tagaz are supplied by Genuine Parts (repacker of spare parts). The main pad manufacturers are Mando and Sangsin. According to driver reviews, they have good performance braking, do not creak, do not spoil the brake disc, and moderately heated. The main factory number of the front pads is 58101-25A10. There are also several SKUs that are factory replacements.
Analogues of the front pads for Accent Tagaz
The original pads are a bit overpriced despite their positive features. Therefore, numerous substitutes are popular. The most popular analogues are presented in the table.
Rear pads for Accent Tagaz
Manufacturers rear pads on the Accent Tagaz are the same as for the front ones. On this vehicle 2 types of drums are installed, which differ in size. Pads are selected depending on the drum. According to driver reviews, they do not differ in special outstanding characteristics, have an average service life, and do not creak.
Analogs rear pads for Accent Tagaz
As with the front pads, original rear pads are expensive. Therefore, you can take a look at no less high-quality, but cheaper substitutes. The most popular analogues are shown in the table.
What are the best pads for Accent Tagaz to buy? If there is a question of quality, then it is better to put the original ones, since they are produced specifically for this car. If it is not possible to overpay, then you should take a closer look at the Hankook Frixa pads. They have a reasonable price, they slow down stably when overheated, and they also have good responsiveness when cold. Still pretty good pads for Accent Tagaz are Hi-Q (Sangsin brand). This model is even cheaper, and has slightly lower parameters when braking in cold weather and when overheating. The rest is no worse, besides, this company supplies the original to the conveyor, which is true, the substitute, in its catalog, has slightly different characteristics.
When to change pads for Accent Tagaz?
According to the Hyundai Accent 2 Tagaz maintenance regulations, the pads are checked at each technical inspection (drum through maintenance). Replacement should be made when the wear of the friction material reaches 70-80%. The minimum allowable wear thickness is 1 mm. The average mileage on the original pads is about 35-40 thousand km - on the front, and 80 - 100 thousand km - on the rear (drum).
We are under renovation Hyundai car Accent (Hyundai Accent), with a 1.5 liter engine, manufactured in 2006, on which it will be necessary to replace the rear brake pads. We will show you how to do it right with your own hands, in garage conditions.
We have drum brakes. Remove the rear wheels and raise the car. We remove the drum, it was not possible to unscrew its fasteners in the standard way, everything turned sour and covered with corrosion, I had to use an impact screwdriver:
With the help of a brake system cleaner in a bottle, we wash off the accumulated dirt under the drum. Everything is cleaned with it very well, while it evaporates almost instantly. Using a metal hook, remove the spring.
Holding your finger from behind, press with round-nose pliers and turn the latches on both sides:
Pliers couldn't do it properly. Further, for the convenience of work, we decided to remove the hub. Using a hammer and screwdriver, knock down the cover:
With a 32 head, we unscrew the hub fasteners:
We remove the pads from below, so as not to damage the anther, remove the remaining spring of the handbrake cable:
We begin to rearrange all the mechanisms from the old brake pads to the new ones, we have them from SANGSIN, the article in the SA-046 catalog.
We put new pads on the car, for this we pull the spring on the handbrake cable with round-nose pliers in the same way, insert it into the pad mechanism:

DESIGN DESCRIPTION
Service brake system hydraulic, dual-circuit (with diagonal separation of circuits), with vacuum booster and sensor insufficient level fluid in the master cylinder reservoir. IN normal mode(when the system is working) both circuits are working. In case of failure (depressurization) of one of the circuits, the second one provides braking of the car, although with less efficiency. Some vehicles are equipped with an anti-lock braking system (ABS). brake pedal - hanging type equipped with a return spring. Above the pedal is a brake light switch; its contacts close when the pedal is pressed. The brake pedal free play should be 3-8 mm.
To reduce the effort on the brake pedal, a vacuum booster is used, which uses the vacuum in the intake manifold of a running engine. The vacuum booster is located between the pedal pusher and the main brake cylinder and is attached with four nuts to the front end shield in engine compartment. The vacuum booster is non-separable; in case of failure, it is replaced. The main brake cylinder is attached to the vacuum booster housing with two studs. A reservoir is installed on top of the cylinder, from which brake fluid enters the cylinder. The tank is marked with maximum and minimum liquid levels, and a signal device with a float is mounted in the tank, closing the contacts when the liquid level drops. When equipped car ABS into holes with right side of the main brake cylinder, two fittings of tubes are screwed in, supplying fluid to the hydraulic
Czech ABS block, from which it is fed through the channels to the working cylinders.
On non-ABS vehicles, pressure regulators are installed on the brake master cylinder. They are designed to limit the growth of fluid pressure in hydraulic drives. rear wheels after reaching a certain pressure in the main brake cylinder. This limits the braking torques of the rear wheels and reduces the likelihood of their anticipatory blocking in relation to the front wheels when hard braking. Accurate testing of the pressure regulator is not possible without special equipment. Anti-lock braking system ensures stability of vehicle control during braking due to the elimination of wheel blocking. The ABS hydraulic unit, consisting of a modulator, a pump and a control unit, is attached to the bulkhead in the engine compartment under the vacuum brake booster. The ABS operates depending on the signals from the wheel speed sensors mounted on the wheels. When the vehicle is braked, the block ABS control determines the start of the wheel lock and opens the corresponding solenoid valve pressure relief modulator brake fluid in the channel. The valve opens and closes several times per second, so you can verify that the ABS is working by slightly shaking the brake pedal. If a malfunction occurs in ABS brake the system remains operational, but it is possible to block the wheels. The corresponding fault code is written to the memory of the control unit, which is read using special equipment in service center. Brake mechanism front wheel- disc, single-piston, with a floating caliper and an acoustic wear indicator on the inner pad. Standard Thickness brake disc should be 19.0 mm, the minimum is 17.0 mm. Maximum allowable end runoutbrake disc size is 0.05 mm. The lining thickness of a new brake shoe is 9.0 mm, the minimum is 2.0 mm. When the lining thickness of the inner pad is less than 2.0 mm, the wear indicator begins to squeak, warning the driver to replace the pads. The brake pads of the left and right wheels are replaced at the same time.
On a vehicle with ABS, a wheel speed sensor (A) is installed in the steering knuckle hole, and a ring gear (B) is pressed onto the drive outer joint housing. Brake mechanism rear wheel- drum, with a two-piston wheel cylinder and two brake shoes, with automatic adjustment of the gap between the shoes and the drum. The standard thickness of the lining of the shoe should be 4.8 mm, the minimum - 1.0 mm. The standard inner diameter of the brake drum is 180 mm, the maximum is 182 mm. Noncylindricality working surface brake drum should not exceed 0.15 mm. The drive of the parking brake system is mechanical, cable, on the rear wheels. It consists of a lever, a rod with an adjusting nut and two cables. The rear ends of the cables are connected to the drive levers parking brake installed on the rear pads. The lever, fixed between the front seats on the floor tunnel, is equipped with a cable tension adjustment mechanism. The front tips of the cables are connected to the equalizer of the tension mechanism. The full stroke of the lever after adjustment should correspond to a rise of 6-7 teeth in the sector.
REPLACING THE BRAKE SHOE OF THE FRONT WHEELS
The brake pads of the front wheel mechanisms are non-_| it is necessary to replace only a set - four pieces. Replacing only one brake pad can cause the vehicle to pull to the side when braking.
If the brake fluid level in the reservoir is at the “MAX” mark, we pump out part of the fluid from the reservoir with a medical syringe or a rubber bulb so that when the piston is sunk into the cylinder, the fluid does not leak out from under the reservoir cap. We remove the front wheel.
